How to cancel Fluid Ui by mail
Collect the details you need
Have the account email, the plan or product name and the invoice or order number from your latest receipt to hand. The details in the letter need to match what Fluid Ui has on file.
Prepare the letter
State plainly that you want the Fluid Ui account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Cancellation Request – [your name]”).
Mail it with tracking
Use certified mail for the A94K5X8 Dublin address in the next section, so the post office records the delivery. Write down the tracking number.
Keep proof the letter arrived
File the receipt with the letter. A Fluid Ui charge dated after delivery is the one to dispute, and these two documents are what you quote.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
