Jepsons review for Omnisend Email Marketing & SMS

Potential to be a great service but the pricing structure is disgusting. To increase the price (in our case £60 to £152.40 per month) irrespective of how many emails are sent is quite underhand and they obviously now it. We don't want to bombard our customers so are often paying this amount to send one or two emails a month. Yes, we could possibly avoid some increases by constantly messing around with our email list, but why? Surely it would be better to charge for the amount of emails sent instead of how many people are on your email list?
