Back to overviewAt Lettermint we promise fast delivery of transactional emails, but how fast is fast? With our new Time to Inbox (TTI) page you get real-time insights into delivery speed.
The Time to Inbox (TTI) shows the current speed of our transactional email infrastructure. We measure the time from sending an email via our API to delivery in the inbox. We perform these measurements at the largest email providers like Gmail, Outlook, Yahoo and more.
We've been using this data internally to monitor our infrastructure and ensure speed. We're so proud of the results that we've decided to make this data public.
For more explanation about Time to Inbox and how we measure it, check out our Time to Inbox page. Here you'll also read why we separate transactional emails from broadcast emails like newsletters and campaigns.
