They cover different parts of the workflow, so this comparison covers what each one does, what each one costs, and where they overlap.
The Quick Answer
MailerCheck is a data enrichment tool for B2B lead data and contact enrichment; Revenue.io is a sales engagement platform for multi-channel sales outreach and engagement tracking.

MailerCheck publishes an entry price of $0/mo; Revenue.io uses custom pricing, so the two cannot be compared on list price.
If your priority is finding accurate contact data for target accounts, MailerCheck is the one built for it; for coordinating outreach across email, phone, and social channels, that is Revenue.io. Many teams run one of each.
Understanding the Core Difference
