Email deliverability, one problem at a time

Warmup, placement test or list clean-up: which do you actually need?

Three tools, three different jobs, and buying the wrong one wastes money without fixing your inbox placement. Answer a few questions, see where your mail really lands, and price it across every mailbox before you commit.

MailReachBest all-in-one

Warmup and a spam and placement tester under one login, billed per mailbox, so one tool covers reputation and evidence.

From $19.50/mo · No free plan, paid per mailboxSee MailReach
GlockAppsBest placement test

Shows where a seed email actually lands across providers, with DMARC analytics, before you decide anything needs warming.

Free plan, paid from $59/mo · Free tier, 2 testsSee GlockApps
ZeroBounceBest list clean-up

Verify and score a list before you send, with a free tier and pay-as-you-go credits, so bounces do not sink a new domain.

Free plan, paid from $99/mo · Free plan, 100 credits/monthSee ZeroBounce

Warmup, inbox placement and list verification tools in one registry: every price and limit comes from the official pricing pages and is shown with the same rules.

Illustration: a person with a notebook stands between three separate stations, a stove warming mailboxes, envelopes sorted into trays and a sieve over a drawer of contact cards

How we work

A choice you can defend

Official prices, one registry

Every amount and limit comes from the vendor's pricing page and is reused everywhere on the site. Prices change; each guide links to the source.

Real screenshots only

Interfaces are the vendors' own published visuals. No mock-ups, no generated images, no invented test results.

One written method

Every verdict applies the same method to the same registry, guide after guide. Read the method.
