As a member, you can choose how you want to receive messages.
The default will be set to what you chose when you created your member account.
You can change this by logging into your online account and going to Account Settings then Manage Your Preferences area.
If you only want to receive emails, you can disable the SMS function. Your connection will be advised that you will only accept emails from them.
Similarly, if your preference is for text, you can turn off email.
The person who invited you to connect via Toppako will set their preferred way to receive messages. They may change their account settings to add or remove email or SMS.
If this happens, you will receive a message with updated contact details.
