We also had our account blocked last year but they never told us why. We don’t sell anything via our newsletter. We don’t even talk about how to make money (that’s not our field). We write about business news and part of our CRM initiative. We sent several email inquiries to them. All were ignored. We ended up setting up a new account and reimporting all of our lists.
To manage expectations, it’s a good idea to send your subscribers a quick follow-up email immediately after they’ve subscribed. This is an optimal opportunity for you to, not only thank them for subscribing, but to also to introduce yourself, send them material that you think they’ll be interested in as new subscribers and remind them how often to expect your messages. Almost all email service providers give you the option to create an autoresponder workflows (something we’ll talk about a little bit later), so use it!
