Live delivery data

Time to Inbox

We measure these delivery times with our own open-source monitor. It sends test emails to inboxes at major email providers and records how long each one takes to arrive. Our engineers get an alert when a delivery takes longer than 10 seconds. Source code is available on GitHub.

Current Delivery Times

We tested delivery ourselves: these figures are data from our own monitor, which sends test messages about every 5 minutes. Direct is a message from our servers to an inbox at that provider. Forwarding is a message to a Forward Email address that forwards it to that inbox. According to our latest test, every message arrived within 6.9s.
