Design pattern for messaging service

Helllo,

I'm looking for a design pattern to implement in Java to meet requirements:

Having a list of Contacts (let's say Contact is an object with some fields)
Single contact record should have information thorugh which channel and which provider message should be send
Depends on situation there could be need to send messages to list of above contacts
There may be possibile different channels (email/sms/slack etc.) and different msg providers (integratio with 3rd party systems: Twilio/Slack/Messenger etc)

Could you please suggest what design pattern here would be most appropriate?
