1. SignoFast
SignoFast is $39/mo or $32/mo billed yearly ($384/yr) for unlimited email accounts, leads, sends, and warmup. LinkedIn is $30/mo per LinkedIn account.
Choose SignoFast when unlimited mailboxes and leads matter as much as multichannel sequences, and you want one Unibox for email and LinkedIn replies.
2. Lemlist
Lemlist is a natural creative peer for Reply.io-style multichannel storytelling. It fits when personalization polish per seller outweighs unlimited mailbox economics.
3. Instantly plus a LinkedIn tool
Some teams split the stack: Instantly Growth near $47/mo for email, plus HeyReach or another LinkedIn tool. That works until ops cost and attribution sprawl become the problem SignoFast was designed to remove.
4. HeyReach for LinkedIn-heavy motions
HeyReach can cover LinkedIn-first playbooks. Pair it with a cold email platform if mailbox volume is still part of the motion.
How to choose among Reply.io alternatives
- Separate creative multichannel needs from unlimited email infrastructure needs.
- Model seat cost vs unlimited workspace cost at next-year headcount.
- Decide if LinkedIn must live in the same sequencer this quarter.
- Pilot Unibox reply SLAs with one pod before a full cutover.
- Migrate sequences that already produce meetings first.
