the platform

Everything email, in four parts.

Use one piece or all four — Tagmail is built so each product stands on its own and gets stronger connected to the rest.

send

Send

Email API and SMTP relay for transactional mail — receipts, password resets, alerts.

validate

Validate

Check addresses in real time or in bulk before you ever hit send.

inspect

Inspect

Preview and QA every email across 100+ clients before it ships.

optimize

Optimize

Inbox placement testing and reputation monitoring, always on.

deliverability

Built to land in the inbox, not the spam folder.

SPF, DKIM, and DMARC are configured for you from the first domain you add. Shared and dedicated IP pools are warmed and monitored continuously, so your sending reputation stays clean as you scale.

validate

Never send to a bad address again.

Every bounce costs you sender reputation. Validate checks syntax, domain, and mailbox status in real time as users type, or in bulk against a list of millions — flagging disposable, role-based, and undeliverable addresses before they ever cost you.
