<b>Warm-up showdown: Instantly vs MailReach</b>

<b>Warm-up showdown: Instantly vs MailReach</b>
Both claim to fix deliverability. They warm differently, and it matters.

Instantly bundles unlimited warm-up into its $37/mo Growth tier — it's "free" because it pools your inboxes into one giant private network. Volume is huge, but the conversations look templated under inspection.

MailReach charges ~$25/inbox/mo standalone and runs slower, more human-looking threads with real reply variation. It also gives you a Spam Test score (X/10) you can act on.

Pros / Cons
— Instantly: cheap at scale, weak per-inbox visibility
— MailReach: clean reports, per-inbox detail, costs add up past 5 inboxes

Who it's for: Instantly if you're running 20+ inboxes and want it baked in. MailReach if you have 1-4 inboxes and want diagnostics, not just volume.

Verdict: 4/5 Instantly for scale, 4/5 MailReach for forensics. Don't run both on the same inbox — competing warm-up signals confuse the algorithms.
