About SendHQ

SendHQ gives product teams and AI agents one coherent email workflow for serious product communication. Teams can verify sending domains, send transactional messages through an email API, receive inbound email, and inspect delivery outcomes from one service. Workspace-scoped API keys help keep access boundaries clear for applications and agent workflows. The public REST surface is designed to make transactional email easier to integrate while preserving visibility into what happened after a message was sent. SendHQ also supports delivery event visibility and inbound routing, so builders can connect outbound messages and replies in the same product workflow. Plans start at $9 per month, with options for transactional and marketing email as usage grows.

Badges

Show that SendHQ is in the index

Optional

Copy a snippet onto your site if you want to. Badges are earned status, not a toll: your listing stays indexed, ranked and dofollow whether or not one is embedded. Add whatever rel attribute suits your site. A badge seen on a live site earns the optional badge partner tag. The smaller badge, in light or dark and small or large, is on the badge page.
