Email Warmup Software
Alternatives to Warmerly
Warmerly brings automated email warmup and deliverability checks into one service. It sends threaded exchanges with quoted replies and natural delays, rescues warmup messages from spam, and checks SPF, DKIM, DMARC, MX, and TLS each day. Google Workspace and Microsoft 365 connect through OAuth; other providers can use IMAP and SMTP. Plans range from a free option with one mailbox and 100 campaign emails monthly to paid plans starting at $19 per month. Android, API, and web access are available, with LinkedIn and WhatsApp as additional channels.

Choosing instead of Warmerly
You may prefer another product for deeper placement analytics, AI-written outreach, website-based prospecting, or a self-hosted setup. Warmerly’s free campaign allowance is limited, and LinkedIn costs separately, so account volume and channel needs can change the calculation. Compare how each alternative warms mail, simulates replies, monitors authentication or inbox placement, connects providers, and handles ongoing sending. Platform coverage, annual billing, mailbox requirements, and whether you manage infrastructure yourself also affect which service fits better.
