With emails in Mautic you can personalize them via curly brace syntax when composing the email. Which will allow your email to be tailored slightly per person.
With SMS and push notifications that doesn’t appear to be supported out of the box with the Twilio and OneSignal plugins. Is this correct or is there a way to personalize that I’m unaware of?
For the benefit of any future forum searchers:
I’ve been looking through the latest code. From the looks of it there is probably complete personalization (ie, tokenization) support for SMS. The SmsModel class dispatches a SmsEvents::TOKEN_REPLACEMENT event, which is picked up by SmsSubscriber::onTokenReplacement, which then uses TokenHelper::findLeadTokens. The latter appears to generically look for tokens.
