How to cancel Lucidchart by mail
Find your account details
Check the account email, the plan or product name and the invoice or order number from your latest receipt before anything else. A request that does not match the account on file at Lucidchart is the easiest one to set aside.
Write your request
The letter asks Lucidchart to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Cancellation Request – [your name]”. Postbye fills it in from our English template.
Post it with proof of delivery
Send the letter to the Melbourne mailing address shown below by certified mail. Keep the tracking number safe.
Keep the delivery receipt
Delivery confirmation is your evidence that Lucidchart was asked. Watch the next statement or two for any further Lucidchart charge.
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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
