Smartlead is genuinely good, and both tools now do warmup and campaigns in one place. Warmerly starts lower, never caps sends, and adds LinkedIn to the same sequence, with WhatsApp in the inbox. Smartlead lists unlimited email accounts and an API feature, which suits custom outbound tooling, but check which of its plans include the API. If you build custom outbound tooling, pick Smartlead; if you want the lower flat price or multichannel sequences, pick Warmerly.
Yes. Leave Warmerly's campaigns off and it only warms the mailbox, while Smartlead sends 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. Free plan, no card required. Paid plans start with a 7-day trial, first charge on day 8, cancel any time before then. We will warm right alongside whatever you use now, so you can A/B without commitment.
