Donation receipting
The receipt goes out the same day, and the log records that it did.
HMRC, Gift Aid
A verbal declaration has to be confirmed in writing, and the donor told they may cancel within thirty days of that confirmation. The clock starts when you send it.

Sample · worked case
The log and the output below are one worked case, at the shape the real run produces.
Same-day receipting is not politeness, it is the clock: the thirty day cancellation window runs from the date of your written confirmation, so a receipt sent three weeks late moves a deadline you did not mean to move. The log entry is the evidence, not the sent folder.
