Great value when it works but omg I just tried to send my first big email (after months and months of sending welcome emails with great response rates) and low and behold Sendfox goes into some kind of 'warm up' mode where they don't. send. the. email. for. an. indefinite. period. of. time. What the heck! :(

I've reached out to support and received a generic response about how they're trying to protect my reputation by only sending my emails to a small amount of people at a time. Sounds great in theory but hey guess what? I have a time-sensitive email that I actually just want to send.

Here are some issues I see with Sendfox's approach:
1. There was no warning this would happen, not even a 'hey if you're sending out an email to this many people it may take X time, are you cool with that?'
2. There is literally no time frame this will be resolved.
3. There is no undo, so even if I wanted to try sending out the email only to 'active' contacts etc. it's too late! I have no idea who has received the test email, and now I can't even go with another service because I don't want to send people the same email twice!
4. Support has been really slow. It's been over 2 days now and my email is still in 'warm up' mode or whatever. In the last 24 hours I have received no word from support but I have receieved wait for it - 2 promotional emails from Appsumo! - So wait... Appsumo is allowed to send promotional emails to me, but I'm not allowed to use their tool to send emails? C'mon guys!

If they changed the name to SendSnail I feel like I would at least have been better prepared :(
