Warmy vs Folderly 2026: Which Email Warmup Tool Wins?

Warmy is a per-inbox warmup tool built around an AI rotation network, but it pulled its pricing off the site in May 2026 and now gates quotes behind a demo call. Folderly bundles warmup with a real-time deliverability score and AI spam-content scanning, but forces a 1-year minimum contract. For a 10-mailbox team, that gap used to run about $490/mo on Warmy's old tier versus $960-$1,200/mo on Folderly's. Warmy is cheaper and flexible; Folderly tells you more in real time.

How much does Warmy cost vs Folderly in 2026?

Warmy's public pricing disappeared in May 2026. Historical tiers ran $49 to $429 per inbox per month for 100 to 5,000 warmup emails a day, per Mailreach's 2026 Warmy pricing breakdown. Folderly charges $120/mailbox monthly or $96 annually for 1-9 mailboxes, dropping to $90 at 10-24 and $70 at 25-99, per Findstack's 2026 Folderly pricing page, plus a 1-year minimum term. Hidden pricing usually means room to negotiate above 10 mailboxes. Folderly's tiers are fixed for a full year regardless of results.

Which has the bigger network and catches problems faster?

Warmy publishes the most detail on network mechanics. Its Adeline AI engine drives inbox rotation and scales individual inboxes up to 5,000 warmup emails a day on its top tier. Folderly doesn't publish a comparable figure, leaning instead on inbox placement testing and a real-time score that catches a reputation dip faster than Warmy's weekly trend lines.

Warmy pulls ahead on scale: its multi-domain dashboard watches every domain from one screen, which matters more at 5+ sending domains than a single live score on one account. Neither tool replaces the free warmup bundled into Instantly or Smartlead, which just cycles emails between your own inboxes instead of routing through an external network.

Which has better DNS and DMARC setup tools?

Warmy checks a wider set of records: SPF, DKIM, DMARC, rDNS, MX, and A, plus free SPF and DMARC generators that catch misconfigurations before they tank a new domain. Folderly monitors SPF, DKIM, DMARC, and MX with fix guidance, but doesn't publish coverage for rDNS or A records. If DNS setup is the actual bottleneck, and for most teams launching a new domain it is, Warmy's coverage wins.

Warmy vs Folderly: which should you pick?

Pick Warmy if you're a small team or agency proving out a new sending domain and don't want a year-long commitment first. Pick Folderly if you run 10+ mailboxes at steady volume, want one real-time score instead of weekly reports, and the contract is a rounding error against your spend.

• Warmy: month-to-month billing, no long-term risk
• Warmy: broader DNS record coverage (SPF, DKIM, DMARC, rDNS, MX, A)
• Warmy: multi-domain dashboard built for agencies
• Warmy con: pricing now hides behind a demo call

• Folderly: real-time score with daily placement tracking
• Folderly: AI content scanner flags spam triggers before send
• Folderly con: 1-year minimum commitment locks you in regardless of results
• Folderly con: entry pricing starts roughly 2x higher than Warmy's old Starter tier

Frequently Asked Questions

Is Warmy or Folderly cheaper in 2026?
Historically Warmy started cheaper at $49/inbox/month versus Folderly's $96 to $120/mailbox/month. Warmy has since hidden its pricing behind a demo call, so get a current quote first.

Does Folderly require a long-term contract?
Yes. Folderly requires a 1-year minimum commitment on every published tier, so you pay for the full year even if you cancel early.

Can I run Warmy and Folderly on the same mailbox at once?
Technically yes, but two warmup tools on one inbox creates irregular sending patterns that can look automated to spam filters. Pick one per inbox.

Which tool has better DNS and DMARC checks, Warmy or Folderly?
Warmy checks a wider set of records, including rDNS and A, plus free SPF and DMARC generators. Folderly monitors SPF, DKIM, DMARC, and MX but stops there.

Warmup tools fix inbox placement. They don't fix a list targeting the wrong buyer, or a domain that was never set up right. That's the part Modern Inbound handles end to end, infrastructure, sourcing, copy, and sending. See how pay-per-lead pricing works.
