Best Practices for SMS deliverability and Avoiding SMS Restrictions
Error and Opt-out Rate Monitoring
- We are focused on helping our customers deliver trusted communications. To make sure that the carrier does not block or suspend the account permanently based on bad usage.
- We will be monitoring the delivery rate of the overall account and be taking proactive measures(as mentioned below) to keep the delivery rate in check:
Violation Email-We will send out an email notification as soon as the account hits the error rate of 8% and opt-out rate of 1%.
Temporary Account Restriction -We will send out a suspension email as the account hits the error rate of 12.5% and opt-out rate of 2.5%.
Please Note:
As soon as the account will hit the temporary suspension all upcoming outbound SMS will be failed till 00:00 AM UTC.
What should we do when we get a violation email?
Stop all your workflows, campaigns, triggers, and/or bulk actions to contacts who have not explicitly opted in to receive messages from the sub-account.
Enable and customize the Opt Out language and SenderID message as per your use case so that all the upcoming messages are not flagged.
Please discuss this with your client to make no bulk communication or messages blast or cold prospecting message campaigns are sent in the near future before we receive your reply to this ticket.
What are error and opt-out rates and good to have a threshold?
A High Opt-Out Rate indicates that contacts receiving your messages have objected, generated complaints, or marked your SMS as spam. A good opt-out rate is typically in the range of 0—1%.
Once the opt-out rate hits 2%, the sub-account will be locked for sending text messages for 24 hours. A High Delivery Error Rate indicates that you are sending SMS to contacts that are no longer in service, are unreachable, or use a non-SMS-capable device such as a landline.
This may also mean that external carrier filters are refusing to deliver your SMS due to bad sending behavior in the past. A good error rate is typically in the range of 0—6%. Once the error rate hits 12%, the sub-account will be locked for sending text messages for 24 hours.
Please Note:
One on One conversation, Test SMS, Resend Message, and MissedCallTextBack are allowed even if the account is suspended.
How to prevent future SMS suspension
The account should be able to send SMS after 00:01 AM UTC the next day after you received the non-compliant email. You can check the best practices below on how to reduce the error rate:
Add Opt Out language (reply STOP to unsubscribe) in all the first SMS sent to a new contact
2. Add Sender information (Introduction of yourself/company) in all the first SMS sent to a new contact
3. Do not send messages to SMS-incapable devices like landlines, enable the Number Validation feature for this. This feature will look up the number before sending out the message and enable and temporary DND on the contact.
4. Avoid sending URLs shortened using a public URL shortener like bit.ly or rb.gy, instead send the original fill link.
5. Make sure the Business Profile, A2P Brand and campaign are registered
as the messaging world is moving towards the direction where with these registrations no messages will be delivered
6. For future website form opt-in setup, please include a checkbox to ensure the lead gives consent when filling out the form if that's where the leads opt-in.
You can type something like this I just grabbed it from another client as an example:
By providing your name and contact information you are expressly consenting to receive communications from COMPANY_NAME or one of their licensed agents, which may include phone calls (including to any wireless number that you provide) including automatic telephone dialling systems or by artificial/pre-recorded messages text message and/or emails for the purpose of marketing insurance products and services including health, medicare and life insurance plans. By providing your information, you understand that your consent is not a condition of the purchase of any product or services, and carrier messaging and data rates may apply. You may revoke this consent at any time by calling us at 1-800-000-000 or by emailing us at EMAIL_HERE to be placed on our do-not-call list.
7. Good to Have: The first message should have the source of how your leads opt in.
8. Good to Have: Add Opt-in language so contacts are actively double opt-in via sms and web form checkbox (reply 1 to subscribe)
Also, sharing a Messaging Policy which will help you further on this.
