Transactional email

Lands in the inbox.

The most-sent, least-loved email

Transactional is the bulk of business email — and the most underserved

Most platforms treat transactional sends as fire-and-forget: push a payload in, get a status back, no intelligence in between. Plink runs it through the same agent network as everything else — so a receipt can carry the right follow-up, and a password reset can never get stuck behind a marketing blast.

One quota, both jobs

Switch the type on the send. Marketing and transactional share one API, one platform, one bill.

Reputation protection

A marketing campaign can never tank your password resets

The cardinal rule of transactional email is that it must never share sending reputation with marketing. Plink keeps them on separate, dedicated IP pools automatically — each warmed, monitored, and protected on its own. A noisy campaign stays walled off from the OTP that has to arrive.
