Mails so
Six ways to run Mails so from a message.
Drive it by message when you need it, or put it on autopilot.
Validate emails
Forward an email or say 'validate this list' to check deliverability, quality, and identify risky addresses
Re-validate anytime
Say 're-check this list' or 'validate again' to get fresh quality and deliverability insights whenever needed
Check email quality
Ask 'which emails are risky' or 'show undeliverable ones' to review validation results in plain English
Validation summaries
Get scheduled digests of email validation activity, including lists of risky addresses and batch success rates
Validate on schedule
Set Notis to validate email lists automatically on a recurring basis: daily, weekly, or monthly without manual submission
Clean before sending
Pair Mails so with your email marketing, CRM, or newsletter tool to validate and clean lists before campaigns
