Our solution requires us to send out emails well beyond the 1K daily limit and possibly attachments. Up to 10K a day is possible for peak periods.
I am now looking at Email Service Providers for a solution. The solution needs us to allow us to be called via an API, as we need to check business rules before executing each mail, also receive bounced results which we can capture and update contact record.
This could easily be done in SF if it wasn't for the 1K limit.
Any guidance will be appreciated :)
