How to cancel Atlantic Business by mail
Collect the details you need
Atlantic Business will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Draft the request
Your Postbye letter to Atlantic Business asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Cancellation Request – [your name]”. It comes from our English template.
Send the letter by certified mail
Mail the letter by certified mail to the St. John's address in the next section, and keep the tracking number.
Save the tracking record
Keep the tracking record with your copy of the letter. If Atlantic Business 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.

Before you cancel Atlantic Business, check these
- 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.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.

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.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
