I've enjoyed Mailgun transactional email as a free user for a while. Lately, Mailgun have changed the policy that only paid users can create ROUTES, which has cut off this experience.
Most times, I do configure Mailgun with my Gmail account to route all incoming and outgoing emails via Mailgun. Now that Mailgun is forcing upgrade to use the ROUTES feature, and the customer I'm working with presently wouldn't be sending more than 200-500 emails per month. I think it's not financially right to force him pay $35 monthly for such.
I'll like to know if there are other alternatives that offer this features for free that allows outbound and inbound emails configured with Gmail.
