The problem: a booking tool that demands an account. The SPF check fails for a yoga studio.

We write notes like this one because the same problems come back. If someone at a yoga studio reads it and avoids a booking tool that demands an account, the note paid for itself.

HTTPS is table stakes, but SPF is where trust actually lives for a yoga studio. A padlock with a misconfigured record behind it is decoration, not security.

The hosting bill for a yoga studio is twelve dollars a month. Their old provider charged eighty and included a page builder nobody used. SPF was broken on both plans.

We document SPF in a shared spreadsheet. It is not glamorous, but a yoga studio can open it on their phone at midnight if something breaks.

Half the meeting with a yoga studio was explaining what SPF is. The other half was agreeing that a booking tool that demands an account should have been fixed a year ago.

After the move, a booking tool that demands an account broke search indexing for a yoga studio. Google kept serving the old pages for another nineteen days.
