Our website sends an email to the customers if the customer:
(a) Places an order (Order confirmation email)
(b) Requests a free sample product (Free sample email)
Currently both emails are frequently stopped by Spam Filters, and customers often complain about this.
The project is to test the emails and then report to us with a list of changes to make.
+ We would like the emails tested in several email filters
+ We would like this carried out by someone with experience in the field. The reason being that we have already given this project to a freelancer and he did not give us much information.
One of the emails is generated by a PHP mail() function and it has a PDF attachment (the order receipt). The other email is generated by auto responder software installed on our office computer (customer completes form at website, website sends email to our office, our office computer has software which then sends an email to the customer).
Please detail if you have had experience in working with emails and spam filters.
