Email verification for developers

Verify before saving

Check email addresses in signup forms, lead forms, and product flows before they reach your database.

Reduce bounces

Catch invalid, disposable, and undeliverable addresses before you send to them.

Protect sender reputation

Stop low-quality addresses from creating delivery problems later.

Improve data quality

Keep your user records and email lists cleaner, easier to manage, and more useful over time.

Built to fit into your workflow

Pay only for what you use

Start with 250 free verifications each month, then use pay-as-you-go pricing with no monthly fees.

Full control over your API usage

Monitor your API usage in real-time. Get detailed reports, including success rates and error logs.

Add verification without the heavy setup

Maileroo gives developers a straightforward RESTful API, clear docs, and SDKs, so email verification can be added without slowing down the build.

Protect your reputation

Catch invalid and risky addresses before you send to them. Fewer bad addresses means fewer avoidable bounces and cleaner sending over time.

Email verification powered by Zeruh

Zeruh is Maileroo’s dedicated email verification product. It checks each email across multiple signals to help spot typos, throwaway addresses, and inboxes that may not receive mail.

SMTP Check

Checks whether the mailbox appears able to receive email.

MX Record Detection

Confirms the domain has mail records set up to receive email.

Syntax Check

Finds formatting issues before an email address is accepted.

Catch-All Detection

Detects domains that accept all emails, making delivery harder to confirm.

Temporary/Throwaway Email Detection

Flags disposable addresses often used for one-time signups.

Role-Based Email Detection

Detects shared inboxes like info@, support@, admin@, and sales@.

Misspellings Detection

Catches common domain typos before they lead to failed sends.

Free Email Provider Detection

Identifies addresses from free email providers like Gmail, Yahoo, and Outlook.

Mailbox Full Detection

Checks whether a mailbox may be too full to receive new messages.

No Reply Detection

Flags addresses that may not accept replies or may not be monitored.

Tag Detection

Detects tagged addresses that use “+” or similar patterns.

Email Quality Score

Gives each address a score based on its verification results.

Email Deduplication

Finds and removes duplicate addresses from your list.

Email Verification API

Integrate our verification service with your applications for real-time email validation.

Bulk Email Verification

Upload larger lists and clean existing email data in bulk.
