mails.so
mails.soMails.so is an email verification service built to confirm whether an email address is likely to be deliverable in real time. It helps businesses reduce bounce rates, improve deliverability, and maintain accurate contact data by validating addresses before you send campaigns or collect user sign-ups. The platform is designed for quick checks at the moment emails enter your systems, so your marketing and onboarding pipelines stay reliable.
When BOBs handle email inputs—like lead capture, newsletter sign-ups, contact forms, or onboarding invites—mails.so enables a quick validation step so you only send to addresses that are most likely to reach real inboxes. This improves deliverability, lowers wasted spend on bounced emails, and protects your sender reputation.
BOBs can also use validation results to steer what happens next: automatically route invalid addresses for correction, prevent them from entering CRM lists, or prompt users to re-check their email during signup. Over time, this keeps customer databases trustworthy, improves targeting accuracy, and strengthens downstream automations that depend on accurate email data.
