What data does Verify Email return?

It returns a deliverability status (valid, invalid, risky, or unknown), a boolean deliverable flag, the reason for the verdict, MX and SMTP check results, disposable, role-based, free, and catch-all flags, a did-you-mean typo suggestion, and a confidence score from 0 to 100.

How many credits does Verify Email cost?

Email verification costs 0.3 credits per address checked. You can check your remaining credits in the SyncGTM dashboard.

How does Verify Email check deliverability?

It validates syntax, confirms the domain has valid MX records, performs an SMTP-level handshake to check the specific mailbox accepts mail, and runs risk checks for disposable, role-based, and catch-all addresses — all without sending an actual email.

What is a catch-all address?

A catch-all domain accepts mail for any address, so the mailbox cannot be individually confirmed. Verify Email flags these as risky so you can decide whether to send based on your own risk tolerance.

Can I verify emails in bulk?

Yes. Pass a list of addresses via the CLI or API to verify them in bulk, then suppress invalid and risky results before importing the clean list into your sequencer or CRM.

Can I use Verify Email via MCP with AI tools?

Yes. Configure the SyncGTM MCP server in your AI tool (Claude, ChatGPT, Cursor, Windsurf) and you can verify email addresses directly from your AI assistant using natural language prompts.
