Texting Best Practices and A2P Regulation

Sending messages to guests is regulated to protect recipients. Much like how SPAM email messages are regulated, so are text messages. To ensure compliance and message delivery to your guests, follow these guidelines.



In order to send messages to guests, your property must have a brand and campaign registered with The Campaign Registry (TCR). Our onboarding team will work with you to ensure that your property has a brand and campaign registered. Registration ensures that your messages are delivered to your guests.

Opting In

In order to send messages, guests should give consent. To send transactional messages, you need implied consent. Guests provide implied consent by doing business with you. In order to send marketing messages, guests should provide explicit consent. The approved method used for explicit consent in the online booking engine exposes a disclaimer, informing the guest they will be receiving messages from you, that data rates may apply, and the message frequency varies.

  • When a guest makes a telephone reservation, we recommend you train your staff to verbally inform your guests to expect messages from the property about their stay.

Opting out

If a guest sends a message with [only] the keyword, the system will automatically opt the guest out or back in. They are not case sensitive.

STOP - This will opt the guest out, and no further messages sent to this guest will be delivered.

START - This will opt the guest back in.

HELP - This will send a message to the guest, letting them know how to use the keywords.

  • We recommend that your first message to guests should...
    • Let the guest know they can reply STOP anytime to stop receiving messages.
    • Introduce the business name and that they have an upcoming reservation with you.
    • Be concise

Glossary of terms:

A2P -  Application to Person. It relates to an application, like ThinkMessenger, sending messages to a person, like a guest.

10DLC - 10-digit long code, such as the ThinkMessenger number you use to send texts to your guests.

TCR - The Campaign Registry, the database where Twilio registers sender brands and messaging campaigns.

It's not possible to send linked text like this as you can with emails. If you need to send a guest to a web page, you will need to send the entire link.

Do not send links that have been shortened using shared public URL shorteners, such as free TinyUrl or Bitly links. US carrier policies strongly discourage the use of shared public URL shorteners, due to the frequency of use by spammers, scammers and other bad actors. The use of these public shared shorteners will result in higher risk of filtering, with no recourse if filtering does occur. Branded links like those from ThinkReservations for the upsell portal and digital registration are acceptable.

  1. Make sure you are signed into to a Google account that has access to manage the business on Google.
  2. Search your business on Google
  3. In the search results, click the "Ask for reviews" button.
  4. In the popup, copy the Review link to use with your ThinkMessenger templates.
    For example: https://g.page/r/CVvhxNYBLC7BEBM/review

  1. Find your property on Tripadvisor.
  2. Note the URL for your property page and your review page. There will be two sets of numbers, followed by the name of the property and hyphens. The name of the property at the end can be removed.
  3. Remove the extra information at the end, ensuring that you keep both numbers intact, then test. It should redirect again to the full URL.
  4. Use the shorter URL for your ThinkMessenger templates.
    For example: https://www.tripadvisor.com/UserReviewEdit-g44460-d78800
