Warming up
Mailreach is a dedicated email warmup and deliverability tool known for bundling inbox placement testing alongside warmup. It covers both in one dashboard, but prices per mailbox — which adds up fast once your sending infrastructure grows.
The cheaper, specialised alternative. Warmup-only, warmup included on every mailbox, daily auth checks, 5-provider placement insight.

Mailreach is a capable warmup tool with a well-built spam testing layer. If that testing dashboard is central to your workflow, it is worth its per-mailbox cost for a small setup. But if you manage 3 or more mailboxes, Warmerly's flat rate is dramatically cheaper for equivalent warmup quality — and deeper auth monitoring on top.
For warmup, yes. Both connect to Gmail and Microsoft mailboxes via OAuth and run active warmup sequences. Warmerly does not have a standalone spam testing dashboard — but it does cover inbox placement through 5-provider seed monitoring. If you rely heavily on Mailreach's dedicated test reports, you would want a separate placement testing tool alongside Warmerly.
Warmerly is flat-rate — $19 for 5 mailboxes, $49 for 25 — so the cost per mailbox falls as you add them. Mailreach charges per mailbox, so its bill climbs with every one. At 10 mailboxes, Warmerly's $49 Growth plan is typically more than 80% cheaper. That delta compounds every month.
Disconnect your mailboxes in Mailreach, then connect them to Warmerly via the same OAuth flow. Choose a ramp curve that matches your current send volume and reputation. No DNS changes needed. Around 2 minutes per mailbox.
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.
