# MailReach review

Email warmup and inbox placement testing tool for B2B cold emailers, priced per mailbox with a free spam checker.

By Noah — last updated & pricing verified October 23, 2026.

> MailReach is a deliverability tool with two jobs: warming up email accounts and testing inbox placement. Warmup connects any mailbox that supports SMTP, with bulk connection for Google Workspace, and has it exchange human-like conversations with MailReach's network of 30,000+ high-reputation accounts, mostly Google Workspace and Office 365, ramping volume gradually to build or repair the reputation of the address, its domain and the IP behind it; MailReach says restoration works in 90% of cases. A reputation dashboard tracks each mailbox and runs domain health checks for blacklists, SPF, DKIM and DMARC. The spam tester has you send an email to a seed list and reports where it landed across 30+ mailboxes by provider, a score out of 10, link and spam-word checks and blacklist status, and tests can run on a schedule with Slack or webhook alerts. MailReach also offers an email verifier, a Co-pilot that reviews content and sending activity, and APIs for warmup and spam tests. It does not send campaigns; it sits beside tools such as Instantly, Smartlead or lemlist.

## Facts

- Website: https://mailreach.co
- Pricing: Free tier · paid from $15/mo (verified )
- License: Freemium
- Platforms: web
- Best for: Warming up and repairing the sender reputation of Google Workspace and Outlook mailboxes used for B2B cold outreach, before and between campaigns
- Standout feature: A warmup network made up mostly of 30,000+ Google Workspace and Office 365 inboxes, the providers B2B prospects actually use, paired with a spam tester that shows placement by provider across 30+ seed mailboxes.
- Biggest weakness: Per-mailbox pricing gets expensive at scale: warming 50 inboxes costs $900/month on monthly billing, while Instantly and Smartlead include unlimited warmup in their sending plans, and because MailReach does not send campaigns it is always a second tool on the bill.
