OR should consider integration with sendinblue so that we can run marketing campaign on existing and past guests and on subscribers. Sendinblue also allows transcational emails as well as sms.
OR offers sms but sendinblue allows very flexible api and with combination of owner rez token it will be awesome.
That could be a very good feature to have. If you are in any form of contact with their support team, you can ask them to write in to help@ownerreservations to start discussion of an integration.
