What You Get

Everything You Need. Nothing You Don't.

All Features

Verification And Reset

Codes and magic links that reach the inbox in seconds, not minutes.

Receipts And Invoices

Clean, itemized transactional mail that your customers can find later.

Account And Security Alerts

The mail your users notice: new device sign-ins, plan changes, refunds.

Daily And Weekly Digests

Batch summaries of the activity people opted in to hear about.

Real-Time Delivery Logs

Every attempt, every response, searchable and exportable.

Automatic Suppression

Hard bounces and complaints go on the list. A bad address is never mailed twice.

Deliverability And Compliance

We Protect Your Sender Reputation Like It's Ours.

Every send is signed, aligned, and rate-shaped for the receiving domain. Hard bounces and complaints go straight to your suppression list, so a bad address never gets a second try. One click unsubscribe on any non-essential mail, and a strict policy against spam, purchased lists, and unsolicited bulk. That discipline is why your codes land in the inbox.
