Where they pull apart

Folderly

Stands out: The product is placement and authentication (SPF, DKIM, DMARC, seed-list inbox tests), not a warmup bot and not a sequencer.

Watch out: Folderly does not send your campaigns. You still need Instantly, Smartlead, or Google Workspace as the actual mail server.

Not the right fit for

Teams that only need a $15 warmup mailbox
Buyers looking for a cold-email sequencer

PlusVibe

Stands out: Personal includes unlimited campaigns, AI sequence writing, and warmup at $37, with API on Business.

Watch out: API, webhooks, and AI reply agents start on Business at $77/mo. Agency is a demo from $497/mo.

Not the right fit for

Senders who need API on the cheapest plan
Teams that want LinkedIn steps in the same sequencer
