- Indicate nature of your contact reason in question, possibly the account/invoice # or any other information that will indicate this is a legitimate contact.
- Confirm that intended recipient is at the indicated number. “Is ------ at this number?” “We are looking to contact -------”
- Use the Odyssey blacklist, Do not message contacts if they opt-out of messages. Have language in you message to allow recipients to opt-out.
- Only text contacts who consented (Opted in) to being messaged.
What not to do:
- Do not, use of public URL softeners or links to questionable websites or domains that do not match your official website. These can appear as spam to many people receiving such messages.
- Do not, use outdated customer databases where phone numbers could have new owners who did not opt in or are not the target of the content.
- Certain phrases or style choices may set off spam filters. This can include ALL CAPS, Unicode characters (such as emoji’s) sent in large quantity.
- Avoid using phrases such as “Exciting opportunity” or “Important Business Matter”. These can be used by spammers to grab attention and due to this are automatically flagged/blocked by many SMS service carriers.
Other things to note.
