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 by Maileroo checks each email across multiple signals to help spot typos, throwaway addresses, and inboxes that may not receive mail.

SMTP Check

Verify the existence of the email address by checking its SMTP server, ensuring it can receive messages.

MX Record Detection

Syntax Check

Ensure the email address is formatted correctly, following standard email syntax rules to avoid common errors.

Catch-All Detection

Identify if a domain is configured to accept all emails sent to it, which can lead to undeliverable messages.

Temporary/Throwaway Email Detection

Detect disposable email addresses that are often used for one-time sign-ups or temporary use.

Role-Based Email Detection

Misspellings Detection

Free Email Provider Detection

Identify email addresses from free providers (like Gmail, Yahoo) to segment your audience.

Mailbox Full Detection

Detect if a recipient's mailbox is full, preventing bounces due to storage issues.

No Reply Detection

Get insights into email addresses that are not monitored or do not accept incoming messages.

Tag Detection
