SMS Configuration

Sender Number

Before you can do anything with SMS in Maxemail you must first have a dedicated virtual mobile number from which your message will be sent, and to handle replies and opt-outs.
A mobile number can be obtained by speaking to the Support Team.

This number will:

• show up as the sender on the recipient's mobile phone.
• allow Maxemail to manage the Global SMS Stop List which helps you follow sending best practices by suppressing numbers who do not want to receive your SMS messages.

Sender Name

Alternatively, SMS messages can be sent from a name. The SMS standard requires that a name is between 3 and 11 characters.

In order to use a name, samples of messages and any URLs that will be used must be provided, in order to pass spam filter blocks with the UK mobile network operators (MNO). Additionally, a Letter of Authority may be needed to provide to MNOs to prove authority to send messages using a brand name. Our Support Team will advise if this is necessary, and the full requirements are listed in SMS registration requirements.

It's not possible for your Recipients to reply to a message sent from a name. Unlike email, the name is not an alias for a number.

To allow Recipients to still opt-out, a virtual mobile number is still required, and the default opt-out message which is automatically appended to messages will be updated to include the number, eg. "Text STOP to 07900900990 to OptOut". 

Default Country Code

Unless you specify otherwise, Maxemail will assume the use of the GB international prefix of (+44).

Maxemail will use the default prefix to validate all imported SMS numbers. Numbers without a recognised international prefix will have this added on import.
