An AI cold email agent that sends from as many mailboxes as you connect, warms each one up before it works, rests the one that starts bouncing, follows an unopened email with a text and a call, and answers "how much is it?" from your own material before it books the meeting. Through your own server, on your own domain, with no per-mailbox fee.

An agent holds as many mailboxes as you give it, and a campaign rotates its sends across all of them, so no single address carries the day's volume. Gmail and Outlook connect with an app password. Anything else is entered as an SMTP and IMAP host. There is no per-mailbox fee, so five addresses across two domains cost the same as one.
Mail is sent through your own server rather than a shared relay, so the sending reputation stays on your domain and nobody else's traffic can spend it. Replies come back over IMAP and are answered from the address they arrived at, by the agent, from the material you gave it.
A reply to a cold email is the whole point, and it is the moment most sequences drop. Here the reply comes back over IMAP and the agent answers it from the same address, from your Q&A pairs, your documents and your data points: "how much is it?", "what do you do exactly?", "send me something". It replies once per thread, and it ignores bounces, out-of-office messages and no-reply addresses, so it never argues with an autoresponder.
When the person is interested, it offers real open slots from your connected calendar and writes the booking in. Every thread lands in one inbox, newest first, tagged with the mailbox it came in on. Reply in any thread yourself and the agent stands down on that conversation; hand it back when you are done.
Each step of a campaign has a send condition: opened, not opened, clicked, not clicked. So the second email goes only to the people who opened the first, and the text on day 2 goes only to the people who did not. The call on day 5, on your own Twilio number, goes to whoever is still silent. Email, text and call are steps in one campaign, not three tools with three lists.
The text step carries the number it sends from, texts per hour for that number, the sending window and the Reply STOP line. A reply, a booking or an opt-out on any channel ends the sequence on every channel and cancels whatever was queued, including the mail.
Opens and clicks are recorded per campaign and written to the person's history, so you can see who read the email before the text went. The dashboard counts people rather than sends: how many the campaign reached, how many replied, how many visited your site and how many converted, with the value won against a goal you set.
A channel table shows where each person first responded and which channel they were on when they booked, so you learn whether the email closes on its own or whether the text after it does the work. One row per person shows every send, open, reply, text and call in order, with the mailbox each one went from.
Cold email software has solved the sending. It has not solved the mornings after. The sequence goes out, the replies come back, and a person has to read them, answer "what does this cost?", chase the ones who said "maybe next quarter", and put the meeting in the calendar. That person is usually the founder, and that morning is usually tomorrow. An AI cold email agent is the sending and the mornings after, in one thing.
Bold Agent Kit gives you one agent with as many mailboxes as you connect, sent through your own server so the reputation stays on your domain. Each mailbox warms up on a ramp before it works, carries a health score out of 100 with the reasons listed, and rests itself when its bounces or spam placement cross a threshold. Campaigns rotate across the healthy ones, inside hourly caps per mailbox and a daily cap per sender, on the days and hours and in the time zone you set. Every campaign email carries a one-click unsubscribe, honoured on the mail already sitting in the queue.
Then it answers. A reply comes back over IMAP and the agent writes back from the same address, from your Q&A pairs, your documents and your data points, and books the meeting into your calendar when the person says yes. When an email is not opened, the same campaign sends a text on your own number, and then places a call. One agent, one knowledge base, one history per person, across all three, and everything it wrote stored with the material it wrote it from.
And there is no per-mailbox fee. The plan is $25 a month or $200 a year for the whole account: unlimited agents, unlimited mailboxes, unlimited contacts and lists. You pay your AI provider for the model at cost, a few dollars a month, and your carrier for any texts and calls you add. Nothing is metered on our side.
The copy is fine and the list is fine. Four things happen between the send button and the meeting.
A new address sends forty cold emails on its first morning and gets filtered by lunchtime, taking the domain with it. Nobody set up SPF or DMARC, nobody warmed the address, and nobody noticed the bounce rate until the replies stopped coming and it was too late to ask why.
The tool charges per mailbox, so the business connects one and pushes the volume through it. Every deliverability problem becomes a domain problem, and the whole outbound effort goes dark at once, usually in the week it was starting to work.
The sequence is automated; the answers are not. "How much is it?" arrives at 9pm and waits until somebody opens the inbox on Tuesday. By then the interest has gone the way interest goes, and the person who replied has had an answer from someone else.
Half the list never opens the first email. The tool sends them a second email, then a third, into the same folder. The text that would have got through, and the call that would have closed it, live in other tools that nobody has time to run alongside.
You build the email agent once. From then on it sends, warms, rests, answers and books on its own, and fetches you only for the conversations you asked it to.
Every mailbox that opts in sends ordinary mail to other warmed mailboxes on a ramp starting at five a day. The receiving side finds it, pulls it out of spam, marks it read and replies to a share. Each address carries a score out of 100, from SPF, DKIM and DMARC, seven days of real sends and bounces, and where its mail is landing, with the reasons listed. Cross a threshold and the address leaves rotation on its own.
A campaign rotates across every healthy mailbox on the agent, inside an hourly cap per mailbox and a daily cap per sender, on the days and hours and in the time zone you set. Each step sends only if the last was opened, or not opened, or clicked. Every campaign email carries a one-click unsubscribe, honoured on the mail already in the queue, and the whole plan is shown before you press Start.
A reply comes back over IMAP and is answered from the same address, from your Q&A pairs, documents and data points, once per thread. Bounces, out-of-office replies and no-reply addresses are ignored. When the person says yes, the agent offers real open slots and writes the booking into your calendar. A reply, a booking or an unsubscribe ends the sequence on every channel.
Open the agent's Email tab and every connected mailbox shows its health score, its warm-up day, its inbox placement and its SPF, DKIM and DMARC checks, with an Active toggle. The score is not a guess. It is built from the sending domain's records, from seven days of real sends and bounces through that address, and from where its own warm-up mail is landing in the network. When a mailbox's bounce rate or spam placement passes a threshold, it is pulled out of campaign rotation automatically, before it damages the domain, and the campaign carries on through the others.
Cold email deliverability is usually the thing you find out about after the fact, from a quiet inbox. Here it is on the screen before you press Start, per address, with the reason a score is what it is, so the fix is a DNS record or a slower ramp rather than a new domain and a fresh list.
Each one answers a problem above, and each one runs without anybody remembering to do it.
Warmed addresses, a health score with reasons, and an automatic rest for the one that slips. Sent through your own server, on your own domain, with the reputation yours to keep.
As many addresses as you connect, rotated, inside hourly caps per mailbox and a daily cap per sender. No single address carries the day, and no address costs extra.
"How much is it?" at 9pm is answered at 9pm, from your material, from the address it was sent to. Then the meeting is offered and booked, while they are still reading.
Not opened on day 0 means a text on your own number on day 2 and a call on day 5. The same agent, the same campaign, the same history on the same row.
Every send, open, click, reply, text, call and booking is recorded against a person and reported as a funnel, per agent and across all agents. This is the part that tells you which step of the sequence is actually working.
The funnel counts people rather than sends: how many the campaign reached, how many replied, how many went on to visit your site, and how many converted, with the total value won and the median time from first email to the booking. Opens and clicks are recorded per campaign and written to each person's history, so a step conditioned on "opened" has real data to run on. Set a goal with a dollar value and a cold email campaign reports what it made, not how many messages it sent.
Below the funnel, a channel table shows where each person first responded and which channel they were on when they converted, so you learn whether the email is closing on its own or whether the text on day 2 is doing the work. A table of pages shows what known people read on your site before they booked. One row per person shows every send, open, reply, text and call in order, and visit triggers close the loop: when someone you emailed opens your pricing page a week later, the agent follows up after a delay on the channel they last used.
Built from the cookie, email address and phone number attached to that contact, so activity months apart on different channels appears on one row.
Page goals and visit triggers require a one-line snippet on your website. Conversations, bookings and manually marking a deal won work without it.
Each of these is usually a separate tool or a separate person, and most of them are priced per mailbox, per contact or per seat. Here they are one plan.

Bold Agent Kit is $25 a month, or $200 a year, for the whole account: every agent, every mailbox, every contact, no seat tiers and no per-mailbox fee. The only other costs are your AI provider's, typically a few dollars a month, and your carrier's if you add text and call steps.
The same agent covers all of these. Most accounts run one per offer, one per brand, or one per client.
A business selling to other businesses from a list it built. Several mailboxes on a secondary domain, warmed and rotated, a three-step sequence with a text and a call for the silent ones, and the agent answering "what do you do?" and booking the discovery call into the calendar of the person who will run it.
A lead generation agency running cold email for several clients. One agent per client, with the client's own mailboxes, domain, knowledge base and calendar, and nothing shared between them. Invite the client into their own agent and they see their threads and their funnel, and nothing else.
A local business emailing past customers or a list of nearby businesses. Pull a segment from the connected CRM or store, or build the list from the sites you browse with the Chrome side panel, and run a short sequence at it from the address customers already know.
Connect the tools you already run and the agent works them like an assistant would: it takes appointments straight into your calendar, writes notes and outcomes back to the CRM, and reads your store to see what somebody has bought before it answers them.
Bookings are real, not guesses. It is only ever given slots that are genuinely free, and it can only take one it actually offered — so it cannot invent a time or double-book you. The same connection pulls a segment of past customers into a list when you want to run a campaign at them.

Any OpenAI APIA new address sending forty cold emails a day gets filtered, and takes the domain with it. Mailboxes that opt into warm-up send each other ordinary mail on a ramp, starting at five a day. The receiving mailbox finds each message, moves it out of spam if it landed there, marks it read and replies to a share of them.
Each mailbox carries a health score out of 100 — SPF, DKIM and DMARC on the sending domain, seven days of real sends and bounces, and where its own warm-up mail is landing — with the reasons listed. A mailbox whose bounce rate or spam placement passes a threshold is pulled out of campaign rotation automatically, before it damages the domain.
Three steps. A cold email campaign is created as a draft and shows you the whole plan, every contact, every mailbox and every step, before it sends anything.
Name it, choose a model and paste your API key. Then give it what it needs to answer a reply from a stranger: your Q&A pairs for "what do you do?", "how much is it?" and "send me something", your prices, hours and lead times as data points, your documents, and the pages of your own site it may link to. Write the email templates and save them: the opener, the follow-up, the last one.
Write the instructions last: how it should talk, what it may offer, and the replies it should hand to you rather than answer. A request for a proposal, a complaint and "who gave you my address?" are the usual three.
Add every mailbox the agent may send from. Gmail and Outlook take an app password; anything else is an SMTP and IMAP host. Switch warm-up on for each and let the ramp run while you build the rest. Check the health score, fix the DNS record it names if one is missing, and leave the Active toggle on for the addresses that are ready.
Then add a number for the text and call steps, the calendar the agent will book into, and the CRM it should read before it writes. Load the list: a CSV, a segment from the CRM, or what the Chrome side panel pulled from the sites you browsed.
Build the sequence: the email on day 0, the second email to openers, the text on day 2 to the rest, the call on day 5. Set the days, hours and time zone anything may go out, the hourly cap per mailbox, and the condition on each step. Read the whole plan on the review screen. Nothing sends until you press Start.
Then watch the inbox. Replies are answered by the agent from the address they arrived at; the ones you named come to you; bookings land in the calendar; unsubscribes are honoured on the queue. A mailbox that slips rests itself and the campaign carries on through the others. Pause at any point and resume later.
One account runs unlimited agents, one per client, and nothing is shared between them. A knowledge base belongs to a single agent, and content from one agent is never used to generate replies for another.
Invite a client by email address and they get their own login, which opens onto the one agent you gave them: its conversations, its numbers, its analytics and a reply box. They cannot see your other clients, your API keys, your settings or your billing. Access is deny-by-default.
No seat tiers, no credit packs, no per-agent or per-channel pricing, and nothing held back behind an enterprise call.

Cold email software sends the sequence and stops at the reply. An AI cold email agent sends the sequence, and then reads the reply over IMAP and answers it, from the same address, from your Q&A pairs, documents and data points, and offers real open slots from your calendar and books the one the person picks. It also carries the rest of the follow-up: when an email is not opened, the same campaign sends a text on your own number and then places a call, so the people who never open mail are reached on a channel they do read. One agent, one knowledge base, one history per person.
As many as you like, and nothing each. An agent holds every mailbox you connect to it, on any domain, and campaigns rotate across them inside an hourly cap per mailbox. Gmail and Outlook connect with an app password; any other provider is entered as an SMTP and IMAP host. There is no per-mailbox fee and no per-contact tier: the plan is $25 a month or $200 a year for the whole account, with unlimited agents, mailboxes, contacts and lists. Adding a sixth address to spread the load costs the same as the first.
Mailboxes that opt in send each other ordinary mail on a ramp, starting at five a day and rising. The receiving mailbox finds each message, moves it out of spam if it landed there, marks it read and replies to a share of them, which is the pattern of a real correspondent. Each mailbox shows its warm-up day on the agent's Email tab, next to its health score and inbox placement, so you can see where a new address is on the ramp before you put a campaign on it. Warm-up is included; there is no separate service or fee.
Every mailbox carries a score out of 100, built from three things: SPF, DKIM and DMARC on the sending domain; seven days of real sends and bounces through that address; and where its own warm-up mail is landing in the network. The reasons are listed under the score, so a low number tells you which record is missing or which measure has slipped. When a mailbox's bounce rate or spam placement passes a threshold, it is pulled out of campaign rotation automatically, before it damages the domain, and the campaign carries on through the other addresses on the agent. Put it back when the score recovers.
Yes, on the mailboxes you switch auto-reply on for. A reply comes back over IMAP and the agent answers it from the address it arrived at, from the material you gave it: documents, Q&A pairs, prices and hours, and the pages of your site it may link to. It replies once per thread, respects a daily cap per sender, and ignores bounces, out-of-office replies and no-reply addresses. Every answer is stored alongside the material it was generated from. Reply in a thread yourself and the agent stands down on that conversation until you hand it back, and the replies you named in its instructions come to you instead.
They get a different channel. Each step in a campaign has a send condition, opened, not opened, clicked or not clicked, and opens are recorded per campaign against each person. So the second email goes to the people who opened the first, and a text goes out on day 2, on your own number through Twilio or one of eight other carriers, to the people who did not. A call on day 5, on your own Twilio number, goes to whoever is still silent. All of it is one campaign on one agent, and a reply, a booking or an opt-out on any channel ends it on all of them.
Every campaign email carries a one-click unsubscribe. Anyone who uses it is added to a suppression list, skipped by every future send, and any message already queued to them is cancelled, and an opt-out on one channel stops the sequence on every channel. The agent also stays inside a daily cap per sender and hourly caps per mailbox, and replies once per thread. Whether a given list may be emailed at all, under CAN-SPAM, GDPR, PECR or whatever applies where you and your recipients are, is your decision and your responsibility, as it would be with any tool. What you get here is the controls, and a record of every send and reply.
It puts the reputation where it belongs, on your domain, rather than on a shared relay where other people's traffic can spend it. The risk of cold email is volume from an unwarmed address with missing records, and that is what the warm-up ramp, the health score and the automatic rest are for. Many people run cold mailboxes on a separate domain from their main one, and the agent does not mind which: connect as many addresses on as many domains as you like, and the score for each is on the screen before you press Start. A mailbox that slips leaves rotation on its own, so one bad morning does not become a bad month.
One subscription, unlimited agents. Most accounts run several, one per job.
Connect the mailboxes, switch warm-up on, write the sequence, read the plan, press Start. It lands, it follows up, and it answers its own replies.
