Mailreach is an email warmup and deliverability testing tool with a network of 20,000+ real inboxes. Pricing starts at $25/month per email account. Strengths: large warmup network, built-in spam test (inbox placement across providers), deliverability score tracking. Weaknesses: more expensive than Warmbox, per-account pricing scales poorly, no cold email features. Best for cold emailers who want warmup plus inbox placement testing in one tool.
Mailreach Review 2026: Pricing, Effectiveness, and How It Compares
Mailreach: Warmup Plus Deliverability Testing
Mailreach differentiates from other warmup tools by including inbox placement testing alongside warmup. Instead of just warming up your account and hoping for the best, you can actually test where your emails land across major providers. This feedback loop makes your warmup more actionable.
Pricing (2026)
| Accounts | Price/Account/Mo | Total/Mo | Key Features |
|---|---|---|---|
| 1 | $25 | $25 | Warmup, spam test, deliverability score |
| 5 | $20 | $100 | Volume discount |
| 10 | $18 | $180 | Volume discount |
| 25+ | $15 | $375+ | Best per-account rate |
All plans include the full warmup network, spam test feature, and deliverability monitoring dashboard.
Strengths
Inbox placement testing. Send a test email through Mailreach's seed network and see where it lands: Gmail inbox, Gmail promotions, Outlook inbox, Outlook junk, Yahoo inbox, etc. This tells you whether warmup is actually working — not just that emails are being sent.
Large warmup network. 20,000+ real inboxes across Gmail, Outlook, Yahoo, and other providers. Larger networks produce more diverse engagement signals, which mailbox providers weigh when evaluating sender reputation.
Deliverability score tracking. Mailreach assigns a deliverability score (0-100) based on warmup performance and spam test results. Track the score over time to see whether your reputation is improving or degrading.
Practitioner note: The inbox placement test is the real differentiator. I've seen teams warm up for 3 weeks, assume everything is fine, then discover half their cold emails land in spam. With Mailreach, you can test before you send real campaigns and avoid wasting prospects.
Weaknesses
Per-account pricing. At $25/account, warming 10 domains costs $180/month (with volume discount). This is significantly more expensive than Instantly's all-inclusive warmup. Budget-conscious operations feel this.
No cold email features. Mailreach is purely warmup and testing. You still need a separate cold email tool (Instantly, Woodpecker, GMass) and a separate prospecting tool. It doesn't consolidate your stack.
Warmup limitations. Like all warmup tools, Mailreach's artificial engagement may become less effective as Gmail and Outlook improve detection of warmup networks. The tool is fighting an ongoing arms race.
Practitioner note: Use Mailreach's spam test feature before every major campaign launch, not just during warmup. Domain reputation can change over time — a monthly inbox placement test catches problems before they impact your real outreach.
Who Should Use Mailreach
Good fit: Cold emailers who want warmup + deliverability testing, agencies managing multiple client domains, teams recovering from deliverability issues who need to measure progress, anyone using cold email tools without built-in warmup.
Bad fit: Teams using Instantly (warmup included), budget operations that can't afford $25+/account, teams sending through ESPs with managed deliverability.
The Bottom Line
Mailreach is the premium warmup choice. The inbox placement testing justifies the higher cost versus Warmbox ($19/account) for teams that want data-driven warmup. If you just need basic warmup without testing, Warmbox or Instantly's built-in warmup are cheaper options.

Frequently Asked Questions
How much does Mailreach cost in 2026?
Starter: $25/month per email account (warmup + spam test). Scale plans offer volume discounts: 5 accounts at $20/each, 10 accounts at $18/each, 25+ accounts at $15/each. Annual billing saves approximately 15%.
Does Mailreach include inbox placement testing?
Yes. Mailreach includes a spam test feature that sends your email to seed accounts across Gmail, Outlook, Yahoo, and others, then reports where it lands (inbox, spam, promotions). This is a unique feature that most warmup tools don't include.
Is Mailreach better than Warmbox?
Mailreach has a larger warmup network and includes inbox placement testing. Warmbox is cheaper ($19 vs $25/account) and has more warmup recipe options. For warmup + deliverability testing, Mailreach is better. For budget warmup only, Warmbox wins.
How long does Mailreach take to warm up an inbox?
Mailreach recommends 14-21 days of warmup before starting cold outreach. Progress is visible on the deliverability dashboard. New domains typically need the full 21 days. Domains with some history may reach optimal scores in 10-14 days.
Is Mailreach worth it if I use Instantly?
Probably not. Instantly includes warmup in all plans. Mailreach's added value is the inbox placement testing, but if your Instantly campaigns are performing well, the extra cost isn't justified.
