MailAssay is an email verification tool that tells you which email addresses are real before you send.
Bad emails on your list bounce. When too many bounce, Gmail, Outlook and others start sending your emails to spam, even the ones going to real people. MailAssay finds the bad addresses first, so you can remove them.
How it works: check one email, or upload your whole list as a CSV file. For each address, MailAssay checks that it's written correctly, that the domain can receive email, and that the mailbox really exists. It never sends an email to the person.
Every email gets a simple result: valid (real and safe to send), invalid (doesn't exist, remove it), risky (can't be confirmed) or disposable (a temporary throwaway address).
Who it's for: marketers cleaning a list before a campaign, sales teams checking leads before outreach, and apps that want to stop fake sign-ups with the API.
Start free with 100 checks every month, no credit card needed.
