How to cancel Dotto One by mail
Find your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Dotto One names the right account the first time.
Set out the request
Ask Dotto One to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Cancellation Request – [your name]”.
Mail it with tracking
Send the letter to the Toronto mailing address shown below by certified mail. Keep the tracking number safe.
Save the tracking record
Delivery confirmation is your evidence that Dotto One was asked. Watch the next statement or two for any further Dotto One charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Dotto One cancellation letter goes
Dotto One lists Bay Street 1033, 320, M5S 3A5 Toronto, Canada as its mailing address.
The envelope is going to Toronto in Ontario, Canada, so the postcode M5S 3A5 must be on the front.
Your details go in a block headed by Account holder, Billing address on file and Email on file, and the opening line is “To Whom It May Concern,”.

Before you cancel Dotto One, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
