Worth knowing
MailReach
- No free plan or free trial is listed; the free spam test is a one-off tool, not a plan.
- The vendor advises at least 14 days of warm-up before sending campaigns, and keeping it running between them.
- Each sending address under a domain needs its own warm-up, so costs grow with every mailbox.
Warmup Inbox
- Pricing is per inbox, so costs grow with each mailbox; volume discounts start from the second inbox.
- Language warm-up, email-platform warm-up and custom templates need Pro or above.
- It does not verify lists or manage DMARC; DMARC help is limited to a free record generator.
