MailReach vs Warmy

MailReach and Warmy are dedicated email warm-up services. Both connect to your mailbox and exchange messages with a network of other inboxes, which open, reply to and rescue your emails from spam. The goal is to give a new or damaged mailbox a history of positive engagement. They differ in pricing, in the extras around the warm-up engine, and in who they are built for.

At a glance

• MailReach is best for sales teams and agencies warming a known number of outreach mailboxes. It costs $19.50 per mailbox a month, with a discount on annual billing.
• Warmy is best for senders who want warm-up bundled with a broad set of deliverability tools. Plans start from $49 a month and are priced by warm-up volume.

Where MailReach is strong

MailReach keeps its offer simple. One plan covers warm-up for a mailbox at $19.50 a month, sending up to 100 warm-up emails a day through a network made up of Google Workspace and Microsoft 365 inboxes. Those are the mailbox types business recipients actually use, which matters for B2B outreach.

Every plan includes at least 20 spam test credits. Each credit runs an inbox placement test and produces a deliverability report. A reputation dashboard tracks where warm-up emails are landing over time, and health checks cover blocklists and SPF, DKIM and DMARC records. An API is available for teams that manage many mailboxes programmatically.

Per-mailbox pricing is easy to forecast. Ten mailboxes cost ten times as much as one.

Where Warmy is strong

Warmy positions itself as a wider deliverability platform. It offers separate tracks for business and consumer audiences: one aimed at Google Workspace and Microsoft 365 inboxes, the other at Gmail, Yahoo and Outlook consumer mailboxes. That distinction is useful if you send to consumers, where most warm-up tools are less relevant.

The platform includes a large seed list for placement testing, an AI assistant that adjusts warm-up settings, a template checker, blocklist and DMARC monitoring, and Google Postmaster data in one dashboard. Pricing is based on the warm-up volume you need, starting from $49 a month, with a custom tier that adds a dedicated success manager. There is a 7-day free trial with no credit card.

Key differences

• Pricing. MailReach charges a flat rate per mailbox. Warmy charges by warm-up volume, from a higher starting point.
• Audience. MailReach is aimed at B2B cold outreach. Warmy also targets consumer mailbox providers.
• Extras. Warmy bundles more monitoring and AI tooling. MailReach stays close to warm-up and placement tests.
• Trial. Warmy offers a 7-day free trial. MailReach promotes introductory discounts.
• Simplicity. MailReach has fewer settings and is quicker to set up.

Deliverability notes

Be clear about what warm-up can achieve. It creates engagement signals for a mailbox, which helps a new address get past the initial period of distrust and can support recovery after a reputation dip.

It cannot make up for bad sending. If your real campaigns go to unverified lists, generate complaints or lack authentication, warm-up activity will not hide that. Mailbox providers look at how genuine recipients respond, and they actively try to discount automated engagement. Google's policies restrict automated use of Gmail, and warm-up networks have faced enforcement before.

Treat warm-up as one input. Authenticate your domains, start real sending at low volume, target carefully and watch reply and bounce rates. Used alongside those habits, a warm-up tool can help. Used in place of them, it mostly delays the moment the problem becomes visible.

Which should you choose?

• Choose MailReach if you have a defined set of outreach mailboxes and want simple, predictable per-mailbox pricing.
• Choose Warmy if you want warm-up plus a wider monitoring toolkit, or you send to consumer mailboxes.
