How to cancel Smartyplus by mail
Note your account details
Start with the account email, the plan or product name and the invoice or order number from your latest receipt, so the request to Smartyplus names the right account the first time.
Set out the request
State plainly that you want the Smartyplus account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – Smartyplus”).
Post it with proof of delivery
Address the envelope to Smartyplus, San Diego, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Send the email copy
Email support@joinsmarty.com with the same request and keep the sent message. The email is fast; the letter is the dated proof.
File the delivery record
It shows the date Smartyplus received your letter. Check your next statement: no Smartyplus charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
Two routes are open, so use them together: the dates on both records show exactly when you asked.
