We have found that guests are much more likely to communicate and respond to SMS messages. Unfortunately this is only available in North America at the moment. Please may we see the introduction of world wide text messaging.
We did a lot of R&D and found that international SMS is a wild west, with deliverability unknown for many countries. We have pivoted to spend time on WhatsApp for Business, which is currently in testing.
Hi Shawn, A slightly later response than one might have liked! Other software companies, don't seem to find this an issue. We hope a WhatsApp solution can be rolled out before too long.
