AI email warmup. Reputation Google and Microsoft trust.
An AI Agent on every mailbox opens, reads, and replies in real threads with real mailboxes in the MailStrike network, in your style and your hours. Reputation that filters trust, and warming that keeps working.
How warming works.
- 01Your mailbox joins the MailStrike network.
Real inboxes on Google Workspace and Microsoft 365, nothing on SMTP servers.
- 02An AI Agent writes and replies as you would.
Two-way threads with other members, about your industry, in your style and your hours.
- 03It does what a person does with mail.
Reads for a human length of time, clicks, marks important, and rescues anything that landed in spam.
- 04Google and Microsoft record a trusted sender.
Reputation climbs and holds. The campaigns you pay for leave from that mailbox.
You set the limits. MailStrike never exceeds them.
Daily volume, the agent's persona, ramp, timezone, and inbox visibility are your settings.
30 a day is the default. Set it per mailbox.
Full volume. Start at 20 to 30 sends a day per mailbox.
Warming settles to about 15 to 25 a day and never stops.
Never above the 24 you set. Never overnight.
Volume climbs on the curve providers expect from a legitimate sender. No spikes, no burned domains.
You set the daily volume and the ramp, and the dashboard tells you how much you can send today.
The defaults are right for most teams. Change a setting when you want to, not because you have to.
Nothing lands in your inbox. Your day to day does not change.
Warming threads are labeled and archived the moment they land. Your inbox shows only your real mail.
The agent sends, reads, and replies on its own, inside your working hours. No approvals, no queue.
The rest of your setup is untouched too: warming runs alongside the tools you already send with. If you send from Smartlead, Instantly, Apollo or GoHighLevel, there is a page on warming for each of them.
Flashman reads every inbox each morning. So you do not have to watch every graph for every mailbox.
Flashman · daily summary08:00 · every mailboxEach day the AI assistant breaks down any unusual trend across your inboxes and says what to do about it.
A slide on one provider for one mailbox is surfaced before it costs you placement.
The read a deliverability expert would give you, every morning, for every inbox, with send volume, tracking, and delay recommendations tied to inbox health.
Google and Microsoft catch templated warmup now. Warming without an agent is what gets a domain flagged.
The MailStrike network. What the pool is made of is the whole point.
The MailStrike network is never resold under another brand, so the mailboxes yours trade mail with are MailStrike customers, not another tool's.
Google and Microsoft score your mail on what their own mailboxes do with it. Not one warming send is spent on an SMTP provider neither of them can see.

One Free Deliverability Test found it. Eleven days of warming took PostNitro from 67% to 100% inbox placement at Google, and it has held since. Read the case study →

Questions that come up most.
What this page raises, answered plainly.

The default ramp reaches full volume by day 21, with noticeable improvement around two weeks. Warming does not stop there: it settles to about 15 to 25 emails a day per mailbox and keeps the reputation where the ramp put it.
No. Warming runs alongside live sending at a daily volume you control, and keeps running at maintenance level once you are sending at scale.
Google Workspace, Gmail, Microsoft 365 and Outlook, each with one click through OAuth. There is no SMTP option: every mailbox in the MailStrike network is on Google or Microsoft, so none of your daily volume is spent on SMTP providers neither can see. Campaigns you send through platforms like Amazon SES, SendGrid, Mailchimp, or Brevo benefit from the warmed domain too.
Not unless you want them to. Inbox visibility is Hidden by default: warming threads are labeled and archived on arrival, so the real inbox stays untouched. You can change it in Settings.
Templated warmup is caught, and the pattern is now the tell. Warming that produces real, varied, human engagement through real Google and Microsoft mailboxes builds reputation honestly, which is why every MailStrike mailbox gets an AI Agent instead of a template.
Yes. Authentication is the entry ticket and warming builds reputation on top of it. MailStrike checks SPF, DKIM, DMARC, and MX when you connect a mailbox and shows you the exact record to publish if one is missing.
