    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.
