Frequently asked questions

You could not find the answer to your question? Ask support.

  • Is Lettermint down right now?

    No, Lettermint reports no incident right now. This page reads the official status page of Lettermint every 10 minutes.

  • Lettermint isn’t working for me, but no incident is reported. Why?

    Status pages are updated by people, often a while after an outage starts, and some problems only hit one region, network or account. If Lettermint still reports nothing, the problem may be closer to home: check your own setup, then contact Lettermint support.

  • How often does Lettermint have incidents?

    Lettermint reported 5 incidents in the last 90 days, the last one on Oct 15, 2026. The history above goes back to Jan 21, 2026, when Phare started recording it.

  • How does Phare know the status of Lettermint?

    Phare reads what Lettermint publishes on its status page, incidents and maintenances included, and keeps their history. It never probes Lettermint itself, so the status is indicative: an outage shows up once Lettermint announces it.

  • How do I know if my own website is down?

    Monitor it: Phare checks your websites and APIs from multiple regions, alerts you on Slack, Discord or email, and hosts your status page, with a free plan to get started.

Phare would have checked your website once by now.
