Each time new contacts are added to a survey, the invitations will be sent out in batches that grow exponentially.

This message means that your contacts are marking your email as SPAM and you need to take immediate action! This article explains which actions you can take to remedy the situation.

CheckMarket blocks the import of email addresses that are known to belong to either a mailing list or spam detection service.

Role-based addresses are typically company addresses defined by a job rather than a person, and are associated with high bounce rates and spam complaints.

If you’ve received a ‘High bounce rate warning’ message, the bounce rate for that specific survey is higher than 5% and email sending has been throttled.

CheckMarket maintains a number of IP ranges from which your email can be sent, and you can figure out those addresses by querying our SPF record.

Here are a list of CheckMarket domains used in surveys. Make sure all of them are reachable if your respondents have limited internet access.

When you send a large number of survey invitations to the same domain you do not want them marked as spam. You can avoid this in several ways.

Bounced emails or bounce-backs are emails that are returned to you because they cannot be delivered for some reason. There are 2 types of bounced emails.

Use your own domain for emails, surveys and reports. This will dramatically increase the trustworthiness of your email invitations and surveys resulting in a higher response rate.

You can review the contacts’ statuses for your survey. At a glance you will be able to see, for example, who has already responded and who hasn’t.

An email that cannot be delivered ‘bounces’ back to the sender. You can easily correct bounced contacts and send a new email invitation to them.
