How to cancel Semlog by mail
Find your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Semlog can only act on a request it can match to an account.
Draft the request
Your Postbye letter to Semlog asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Semlog”. It comes from our English template.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 87110 Albuquerque. Keep the tracking number it gives you.
Save the tracking record
Keep the tracking record with your copy of the letter. If Semlog bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Semlog cancellation letter goes
Semlog takes its post at 1209 Mountain Road PL NE, Suite N, Albuquerque, NM 87110, which is where a cancellation letter belongs.
Put ZIP 87110 on the envelope: Albuquerque is in New Mexico, and a domestic certified letter is all it takes.
The letter greets the reader with “To Whom It May Concern,”; your own details sit under the labels Name, Address and E-mail.

Before you cancel Semlog, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
