I've got a similar problem. Sending the first few newsletters to a handful of subscribers worked, after that, I've kept getting errors. The log file states that my sending domain “is not allowed to send large batches yet”.
Mailgun Support:
After further review, your account was automatically placed on an evaluation period, which enforces the following limits on the account: a maximum of 100 messages per hour, a maximum of 9 recipients per message, and disabled usage of email validations. To help protect our customers against spam, we have automated systems in place to flag accounts that appear suspicious. On most occasions, this process works very well; however, sometimes we get it wrong and flag a genuine account. There are a number of factors that contribute to the flagging of the account for business verification, but they are not necessarily directly related to you.
I mean wtf: 9 (NINE) recipients per message? This is nuts. (My blog has 11 subscribers)
A few e-mails later, this is my current state:
To establish sufficient sending history with Mailgun and conclude the evaluation process, please conduct normal business operations with 3-5 days of consistent sending. We require your recipient email addresses to be collected organically and for those recipients to be double opt-in recipients. That means that they provided their email address directly to you themselves and have agreed to receive your correspondence. Once achieved, please update this ticket so that our team can re-evaluate the account and remove the sending limitation.
"normal business" for 3-5 days equals "do nothing" when you have a personal blog and write only occasionally new posts, maybe one or two a month.
Anyone else with similar experiences?
