MailerCheck
Email list verification and deliverability testing tool
MailerCheck is an email verification and deliverability testing tool that helps marketers and businesses maintain clean email lists and improve campaign performance. It addresses the problem of poor deliverability caused by invalid addresses, spammy content, and uncertain inbox placement, which can harm sender reputation and reduce ROI.
The tool offers three main capabilities: Email List Verification to validate single addresses, upload entire lists, or verify in real time via an API; Email Insights to analyze content for spam words, broken links, and blocklist issues; and Inbox Placement to test deliverability against major providers like Gmail, AOL, and Yahoo. It integrates with platforms such as MailerLite, Mailchimp, ActiveCampaign, GetResponse, ConvertKit, Zapier, and Make.
MailerCheck is designed for email marketers and businesses of any size that send campaigns. It uses a credit-based system: one credit verifies one email, while Email Insights and Inbox Placement each cost 200 credits per test. New accounts receive 10 free credits to try list verification. Credits never expire, and there is a minimum purchase of 1,000 credits.
