Let agents run your transactional email on Postmark
QX sends templated mail, watches deliverability, and fixes problems before they snowball—so your team ships features instead of babysitting bounce reports.
Stop hand-rolling transactional email, chasing bounces, and digging through delivery logs. Hand it to an agent.
Templated email, on autopilot
Agents pick the right template, fill in the merge fields from your live data, and send batches of up to 500 at a time—no engineer in the loop.
Catch problems before customers do
Bounce spikes, spam complaints and open-rate dips get flagged the moment they appear, with the likely cause already diagnosed and the right people pinged.
A clean list, kept clean
Hard bounces get suppressed, complainers get respected, recoverable addresses get reactivated—your sender reputation stays healthy without anyone touching the dashboard.
