Each time a user attempts to send a campaign, our abuse prevention system evaluates the content for potential fraud. If our system determines there is a high risk, we will prevent the content from being sent.
Why We Do It
Inbox providers look closely at content to ensure a sender isn't trying to "trick" recipients into doing something they shouldn't. For example, a phisher posing as Paypal to obtain sensitive information such as usernames, passwords, and credit card details.
When an inbox provider determines that an email or a sender is trying to trick recipients, they will start to filter messages to the spam folder or block them completely. We check all campaign email templates before sending to maintain the health of our overall email system.
What You Can Do About It
Make sure your templates direct people to domains that reflect your brand, like your website or your social media accounts. Make sure your content is straightforward, so a recipient can clearly understand who you are, what you're selling or sharing with them, and what next actions they should take (e.g. buy, or visit your website). Don't pretend to send email posing as another company, or send your subscribers content that is very unrelated to what they opted-in to receive.
If you believe your template was blocked in error, please reach out to us for help.
