If you have an opt-in list with mobile phone numbers, you should manage any cancellations or so-called opt-outs by removing them from your list of contacts. You can do it by either:
- Setting up a opt in / opt out Flow which will do it automatically.
- Manually removing contacts from your MessageBird Account.
Manually remove mobile numbers from your contacts
To remove any mobile phone numbers from your list of contacts, just follow the steps below.
Step 1: downloading an export of your (sent) messages
Browse to the Messages section within your MessageBird Account and go for the Export tab. Select the month you want to check for opt-outs and hit the 'Export' button.
Step 2: filtering mobile numbers from the exported CSV file
Open the CSV file in your favourite spreadsheet software, and start off by setting a filter on the top row. Select row number 1 and hit the filter button that looks like a funnel, as visualised in the image below.
After the filters are set, move your mouse cursor over the drop-down button on the Inbox cell and select 'yes'. This way, only incoming messages are visualized. Then set a filter for the Messages cell and search for words like stop, opt-out, cancel and other variations, to just show relevant messages.
You can tell your recipients to reply just the word 'STOP' to any of your messages if they would like to opt out. This will speed up the process of filtering your received messages by sorting them in ascending order and browse to the messages that start with 'STOP'. If the message is sent from a shared short code, your recipient should always start the message with your keyword.
Step 3: removing cancellations from your contacts
Once all relevant messages are visualized in the CSV file, select the phone numbers within the ReceiverGsmNumber column and copy them.
Now head back to your MessageBird Account and browse to the 'Import text' tab within the Contacts section. Then paste the copied mobile numbers in the Text field, select the remove contacts radio button and choose whether you want to delete the contacts as a whole or from a specific group.
We highly recommend you to offer your customers a clear and easy way of opting out from your service, such as given in the tip to tell your customers to reply with the word 'STOP'. Another way is to provide an email or web address in your SMS messages that your customers can use to opt-out from your service by entering their mobile number. It's important that you remove the number from your database as soon as you receive their notification.
