There are some drawbacks to using hosted email marketing services to manage your promotions.
Firstly, you need to abide by their rules and guidelines. For example, some services have rules on what you can promote and what you cannot promote.
Secondly, many hosted services have restrictions in place for importing subscribers in order to protect their delivery rates. Therefore, if you are moving to a new hosted service, you may be forced to make all subscribers opt-in to your newsletter again or at the very least email them and ask them if they want to opt-out. Both of these scenarios can lose you subscribers.
Lastly, but perhaps most importantly, hosted email marketing services can be very expensive. A service such as Aweber charges $49 per month for up to 5,000 subscribers, $69 per month for up to 10,000 subscribers, and $149 per month for 10,001 to 25,000 subscribers.
In contrast, using a self-hosted email marketing solution and sending emails through an SMTP relay service such as Amazon Simple Email Service (Amazon SES) costs $0.10 per 1,000 emails sent. Switching to a self-hosted email marketing platform could save a business thousands of dollars every year which is why so many people are trying out self-hosted email marketing solutions.
