Stopping those emails
One moment.
That link is incomplete.
The unsubscribe link carries a signature so nobody can unsubscribe an address that is not theirs. Yours seems to have lost part of it, which usually means an email client wrapped it across two lines.
Copy the whole link again, or just reply to any email I have sent you with the word stop. That works too and it reaches a person.
Done. will not get the follow ups again.
That stops the two follow up emails: the one about your weakest gate, and the ninety day reminder to run the baseline again.
It does not stop a reply to something you send me. If you email me a question, you will get an answer, because that is correspondence rather than marketing.
What happens to your details
Your address stays on a suppression list, which is the only way to reliably not email you. Nothing else is kept for marketing. If you would rather I deleted everything, say so and it goes the same week, no reason needed.
That did not go through, and I would rather tell you than pretend.
Try again in a minute. If it keeps failing, reply to any email I have sent you with the word stop, or tell me here. Either reaches me and I will do it by hand the same day.
