Mandrill gives 12k free emails per month.
Sendgrid gives another 12k free emails per month.
… and there are more of such providers.
It would be cool to sign up with a few and enter the corresponding SMTP authorization details of all of them in a config file and set a quota, i.e:
- Mandrill: username, password, 11900 (first 11900 emails)
- Sendgrid: username, password, 11900 (next 11900 emails)
- ProviderX: username, password (all the other emails)
For a growing community, would save at least $10/mo * 12mo = $120/year. The figure is especially sensitive in developing countries like Ukraine, and especially for non-profit communities.
