Hey folks, cofounder of Sendwithus.com here -- we&#x27;re a layer on top of Mandrill, SendGrid, Sparkpost, etc. You can hot swap backends with us, making a change trivial. We&#x27;re also experts on all these platforms so can advice cost vs support.<p>Hit our support team (support@sendwithus.com) if you have any questions, we have a super rich feature set that goes beyond what these products provide.<p>Happy to discuss discounts for folks making the switch to us, email me: matt@sendwithus.com
