§ My domain has been pending for an hour.
Check the records again at https://dnschecker.org; the propagation snapshot there is more useful than any single registrar's dashboard. Common causes: an MX record written as the apex of a subdomain rather than the root zone; a CNAME written as a TXT by accident; a trailing dot on the value the registrar has stripped.
§ My letter bounced with “sender not authorised”.
SPF is almost certainly missing or malformed. Open /app/domains/<fqdn> and look for the SPF row — if its status is anything other than resolved, republish exactly the TXT value we show, with no modifications.
§ Reply went out as the wrong self.
The From on reply is derived from the To of the original, not the From. If a newsletter was addressed to subs@your-domain and you wanted to reply as hello@your-domain, you needed to pick the From from the dropdown before sending. We're working on a mail rule to automate this; for now, it's manual.
§ A letter I was expecting never arrived.
First, ask the sender whether they received a bounce — if yes, it's almost always a DNS issue on your end. If no, check Trash (letters from previously-spamming senders are auto-trashed). If still no, check the Quarantine panel at /settings/quarantine; strict DMARC has held it for review.
§ The margin stripe is grey.
A grey stripe means the letter arrived at an address that is not bound to any of your identities — typically a catch-all, or a newly-added alias the frontend hasn't yet fetched. Hard-refresh the inbox. If the stripe stays grey, file a note from /help; we'll investigate directly.
