Verdict
ZeroBounce makes the list as a top-tier email validation service that has successfully expanded its offering to include a useful, though basic, set of deliverability tools available as an add-on to its core product.
What customers praise
The pay-as-you-go pricing for all its services, including the deliverability toolkit, provides great flexibility for teams with fluctuating needs.
What customers criticise
The deliverability tools are not as mature or feature-rich as those from specialized providers, serving more as a convenient add-on than a main reason to choose the platform.
Best for
Marketers who primarily need an email verification service but want to add on basic deliverability tools like inbox testing and blocklist monitoring.
