Median open rate
46.7%
Median click rate
8.5%

The median across 1 newsletter with 200 or more emails delivered, so one sender can't move it. Bot opens and clicks are left out, but Apple Mail opens emails for its readers, so read opens as a trend.

  • Your emails prove they come from you. The Domains page gives you SPF, DKIM and DMARC records and checks them live.
  • New domains warm up. 200 emails on the first day, doubling each day, with no cap from day 13.
  • Your list stays clean. Typos, throwaway inboxes and domains without a mail server are refused at signup; imports skip them and say why.
  • Bounces are sorted. Hard bounces and complaints suppress the address for good; a full mailbox or DNS failure only for a few days. Deferred mail is retried for 26 hours.
  • Complaints are traced to the newsletter. Every email carries its own tracking ID and one-click unsubscribe, and bounce and complaint reports come straight back into the app.
  • Blocklists are watched. Sending domains are checked every 6 hours; a listed domain pauses sending and alerts admins.

How we count

Counted: every real email we sent in the last 30 days: newsletter issues, automation emails, welcome and confirmation emails and other account email. Left out: test emails, and emails that were never sent because the address was suppressed.

The delivery rate is delivered out of delivered and hard bounced. Bounce and complaint rates are out of emails sent. Complaints come from mailbox providers' feedback loops; Gmail doesn't report complaints one by one, so Gmail complaints only show here when they reach the install through a feedback report. Open and click rates are medians across newsletters with 200 or more emails delivered in the period, with bot opens and clicks left out. Numbers show once 500 emails are behind them. Weeks start on Monday, in UTC.
