The top Mailivery alternatives for 2026
MailReach
MailReach combines email warmup with a spam placement tester. One subscription both builds sender reputation and shows where messages land. It is popular with cold-outreach agencies and SDR teams. Pricing starts from $19.50 per mailbox per month.
Best for: Outbound agencies that want warmup and spam testing from a single vendor at a per-mailbox price.
Folderly
Folderly is a full-service deliverability platform. It audits domain setup, fixes authentication, and runs continuous warmup. It also includes placement testing. It targets mid-market and enterprise outbound teams. Pricing starts from $96 per mailbox per month, billed yearly.
Best for: Mid-market teams whose deliverability problem is structural (DNS, authentication, content) rather than just cold mailboxes needing warmup.
GlockApps
GlockApps is a deliverability testing and monitoring suite. It covers seed-list inbox placement tests, DMARC analytics, and blacklist monitoring. Email marketers and ESP operators use it to prove where mail lands. Pricing starts from $0.
Best for: When you need to prove and continuously monitor inbox placement across providers, not primarily to warm mailboxes.

Frequently asked questions about email deliverability
Is Mailivery worth it for small teams?
Mailivery's volume-based pricing can be very cost-effective for small teams with a few mailboxes. This is true especially if their daily send volume is consistent and within the tiered caps. However, consider its smaller network compared to some alternatives for broader signal diversity.
MailReach vs. Folderly: which is better for agencies?
MailReach is a strong choice for outbound agencies focused on warmup and integrated spam testing at a per-mailbox cost. Folderly is better for larger agencies or mid-market clients with deeper, structural deliverability problems. These problems require a full audit and ongoing management beyond just warmup.
How much should I expect to pay for email warmup?
Pricing varies significantly. Basic warmup tools like Warmbox or Warmup Inbox start around $15-20 per mailbox per month. More comprehensive solutions integrating spam testing or full deliverability audits, like MailReach or Folderly, range from $20 to over $100 per mailbox per month. This depends on features and scale. Mailivery offers volume-based plans starting at $29 per month.
