MailerCheck vs. OrbiSearch

Reach the inbox and boost your deliverability by verifying, analyzing and cleaning your email lists. MailerCheck is an email deliverability platform that provides businesses with tools to improve their campaigns and email configuration for maximum delivery performance. The email verification tool allows users to check a single email address or an entire contact list. It detects invalid or problematic emails so they can be removed, preventing damage to the sender's reputation and improving their chances of successful delivery.

OrbiSearch is an email validation tool that specialises in catch-all (accept-all) domain resolution. It verifies whether individual email addresses or bulk lists are deliverable before outreach, helping users reduce hard bounce rates and protect sender reputation. Core functionality: OrbiSearch uses a two-layer verification process. The first layer performs standard SMTP validation — checking email syntax, domain existence, MX records, and basic mailbox reachability.
