SendFox

SendFox is easy to use, and campaigns are straightforward to send.

However, the issue with having a list of, say, 180 people and yet the email only gets sent to 46 is extremely frustrating. Even if they all JUST joined from a giveaway. They're just dead leads.

Also, I've been using for a while and there have been no design-focused updates, which makes it less and less competitive as other email senders expand their offerings to understand that people rarely read emails these days if they aren't visually appealing. I would LOVE to see some increased user opportunity to add even simple design.

I like the pricing structure compared to others, though. I also like how you can categorize your audience.
