I like that it integrates with our CRM system, which is great for us since we send out multiple emails per week. It's also easy to use and has a lot of features. There are some things I don't like about it, but they are minor issues. The only thing I dislike about flowmailer is that sometimes it doesn't send an email right away after you click send. Sometimes it takes up to 30 minutes before it sends. I would recommend this product to anyone looking for a good email marketing tool. We have been using it for over 3 years now and haven't had any problems with it. Our sales team uses it to send out weekly newsletters to our customers.
