To help protect our customers against spam, we have automated systems in place that flag accounts that contain elements that could be considered suspicious.
Most of the time this works pretty well; sometimes though, what the system deems as potentially suspicious is perfectly innocent, and so we end up flagging a genuine, decent account. There are a number of factors contributing to this; as is so often the case in email, there are many variables.
So - if you see this message, not to worry; it's not a comment on you or your business. It might not even be something directly related to you; for example, it could be you're happening to use an IP that was flagged as suspicious in the past. These things happen - we're just making sure everything's alright.
If you see the "Business Verification" message, we ask that you contact our Support team via the Support tab in your Mailgun control panel. To make the process as quick and painless as possible, because we're really just looking to verify you're a quality sender, please provide the following information, so that we can best understand your needs:
What types of emails will you be sending - transactional or marketing? Please tell us briefly about how your business uses email.
Where do you source your database/list of email addresses? Also, please provide any available URL(s) to the website(s) you'll be using with Mailgun.
Are all of your email addresses double-opt-in? (This means that the user has requested your emails through sign-up and then confirmed via email that they want to receive your communication).
What is your expected monthly volume of messages?
Have you read our Email Best Practices document?
Please provide a sample email you would typically send to your users.
As mentioned, we're doing this not to hassle you, but rather to help protect all the users on our system. Business Verification is in place so that we can make sure to give quality users a thumbs-up, and quickly prevent those not practicing good habits from getting in and ruining everyone else's success.
If any questions arise, just reach out to our Support team via the Support tab in your Mailgun control panel!
