Smartlead is genuinely good. The decision comes down to whether you want one tool for both warmup and campaigns. If yes, Smartlead. If no, Warmerly will save you roughly half on the warmup half.
Yes. Warmerly only warms the mailbox. Smartlead can run campaigns from the same Gmail or Microsoft account.
Not directly, but the mailbox reputation persists in Gmail and Microsoft regardless of which tool you use. Warmerly's first health snapshot will reflect that reputation within 24 hours.
Connect a mailbox to Warmerly in 60 seconds. 7-day free trial, card required, first charge on day 8. We will warm right alongside whatever you use now, so you can A/B without commitment.
