Integrations with other email providers

Hi,

We are currently paying a huge amount for Mailchimp, where other email marketing options offer better tools for a fraction of the cost. For example Sendinblue would reduce the monthly cost by about 90%.

However we feel that we need to stay with Mailchimp because of the TS integration, where we subscribe ticket buyers to our mailing list.

It would be great to see another choice of integration! 

Cheers,

Seamus
