Unfortunately, we've had problems with scammers opening up accounts with stolen credit cards in order to use our mail servers to send out spam and phishing mail. We've had to put several measures in place to stop this problem, and we've succeeded. The scammers have moved on.
One of those measures is a limit on how many emails you can send until we've been in touch with you.
You don't need to worry about it. We'll never prevent you from getting another opt-in, and we'll warn you well ahead of the limit becoming an issue for you. Once it does, Simplero will let you know that it's time to raise the limit, and will notify you of exactly what to do to raise it.
We promise to be quick to raise the limit, once you've sent us the information that we ask for.
It's all handled pretty seamlessly. Just go with the flow, and it'll all work out.
