I'm planing several newsletters for one of my project.
The goal is to send out automated daily and weekly as well as sporadic manually sent Newsletters out to several mailing-lists.
Now as I know there actually are two ways to do that: use an external service like MailChimp or CampaignMonitor (which is better?) … or use a service on our own servers.
There are several modules to link ee with an external service and there are the native or local modules like EE Mailing List and FireMail. I know that using an external service might be better because of all the mailing/blacklist/whitelist/etcpp stuff … but what are the disadvantages of those services?
The Project I'm talking about has almost 10k members and therefore there may be thousands of subscribers. The raw-data of the newsletter will be ee-templates and should be (if possible) send absolutely automaticly each day (list 1) and weekly (list 2). There will also be several mailing-lists where newsletters will be sent only manually by me/our staff.
Now since there are so many Services, Modules etc out there: What is the best solution for this use-cases? And why? What are you using? And why are you using that? Or what are your experiences with that particular solution?
