Which One to Pick
4 switching profiles: which alternative fits
Folderly is the clearest fix. Inbox Insights is $79/mo flat for 100 tests with no credit overages or DMARC volume tiers.
MailReach at $25/mailbox/mo wins if you have few inboxes. Folderly at $79/mo flat is better for higher test volume.
Warmbox at $15/mo covers automated warmup via 35,000+ inboxes plus DNS and blacklist audits. Skips multi-provider placement testing, which rarely matters for warmup-only teams.
Start with Folderly. The free Pulse monitoring gives immediate inbox placement visibility before you commit to the $79/mo Inbox Insights plan.
