Worth knowing
InboxAlly

- Plans are sized by seed emails a day; the vendor suggests about 5 seeds per 100 emails sent to the domain being repaired.
- Phone support, setup sessions and strategy reviews start on the $1,190 Premium plan.
- The vendor says repair usually takes 4 to 8 weeks, longer than the 10-day trial.
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.
