    Actually, screw my previous comment. I take it back. They require business verification, and you have to jump through all these hoops for them to allow you to use their service, then beg them "oh pretty please" let me use your service oh wise Rackspace gods. Sod that, no time for that.

    Update: managed to get second email confirmation working after being in touch with them via twitter, and decided to go with them due to mailgun's annoying company verification stuff which put me off.

    This is definitely my favourite of the lot. Very good service, as to be expected from Rackspace. But also pretty cheap, which isn't so much to be expected from them!

    I tried to add a second email to my account and it went straight into spam. Then the confirmation link inside didn't work (404). Then whitelisting my local domain didn't work, so now I'm stuck. Therefore, I have no interest in going any further as I can't be bothered waiting around for them to fix things.

    I bought sparkpost and they have some problem working with interspire which i got to know later. I asked them to give me time to fix things as i use interspire and you are the only one who need a patch to be added. Neither they refunded and keep billing me for no use. and nor they replied to my request. Handle with care.

    Last week, I redeemed all my free open credits. Can't believe that the opened emails are really free. Ur experts consultancy really worked for us. The open rate is now improved and cost is going down. Keep updated us with more tips, we want more emails to be the most customer engaging.

  • suggested on Pepipost to set Price to 1 USD per 5000 emails
    Pepipost is built on the philosophy to encourage Good senders and to keep the email eco-system clean. Quora is one of such good sender. 85% of today's world email is spam, and we don't want to add up to that. We have carried up that philosophy into the pricing model too, where you only pay for emails that are not opened by your customers. Emails that are clicked, opened or enagaged with will always be free (Industry stats says 35-40% is the average open rate) For startups, we have a free plan where they get to send 25K emails free every month forever.
