Warm up your Smartlead mailboxes with MailPilot
MailPilot is a standalone warmup layer that runs alongside Smartlead — it does not plug into Smartlead, and it doesn't need to. You connect the same mailboxes (Gmail/Outlook via OAuth, or ESP/SMTP via SMTP/IMAP) to MailPilot for warmup and inbox-placement monitoring, then send your sequences from Smartlead. The key is to run warmup in only one tool per mailbox: turn Smartlead's built-in warmup off for those inboxes and let MailPilot handle it, so you get real placement data instead of just a warmup score.
How it works with Smartlead
Connect the mailbox to MailPilot
Add the same Gmail, Outlook, or SMTP mailbox you send Smartlead campaigns from — via OAuth or SMTP/IMAP — directly to MailPilot.
Disable Smartlead warmup on those inboxes
Run warmup in one place only. Turn off Smartlead's native warmup for the mailboxes MailPilot manages so the two don't double-send.
Warm up and check placement
MailPilot warms the mailbox and shows real inbox vs. spam placement across providers — data Smartlead's warmup score doesn't expose.
Send from Smartlead when ready
Use MailPilot's outreach-ready status to decide when to launch your Smartlead sequences from that mailbox.
Why warm up alongside Smartlead
Smartlead's bundled warmup gives you a score, not placement results. MailPilot shows where your mail actually lands — Primary, Promotions, or spam — so you know the mailbox is genuinely ready.
Running warmup in two tools at once double-sends and muddies your reputation signals; using MailPilot as the single warmup layer keeps the sending pattern clean.
MailPilot works with any sending tool, so if you later add or switch sequencers, your warmup and placement history stay put — they live with your mailbox, not with Smartlead.
Smartlead warmup FAQ
Can I use MailPilot and Smartlead together? +
Yes — that's the intended setup. MailPilot warms up and monitors the mailbox; Smartlead sends your sequences. Just disable Smartlead's built-in warmup for those mailboxes so warmup runs in one place only.
Should I turn off Smartlead's warmup? +
For any mailbox MailPilot is warming, yes. Running two warmup systems on the same inbox double-sends and confuses reputation signals. Let MailPilot handle warmup and keep Smartlead focused on outreach.
Why add MailPilot if Smartlead already warms up? +
Because Smartlead shows a warmup score, not real inbox placement. MailPilot tests where your emails actually land across Gmail and Outlook and gives an outreach-ready status, so you're not guessing before you scale.
