Your template.
Their email.
Render React Email to HTML, or use a published template. Personalize transactional email with values from your app, and send campaigns to opted-in audiences.
Every email.
A clearer picture.
Follow delivery over time and trace a bounce to its receiving-server response. Delivery events confirm server acceptance; Inbox Insights provides sampled placement estimates.
Trace a bounce to its reason.
Inspect bounce types and receiving-server responses for the period that needs attention.
Receive the reply.
Build what happens next.
Receive email on your domain or a forwarding address. Use the webhook’s message reference to fetch the body and attachments. Give an agent a persistent mailbox to follow threads and reply.
Scale without
losing control.
Organize teams in workspaces, control API access, and trace changes through audit logs.
