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

High complaint rate warning
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.
Domains blocked from import
CheckMarket blocks the import of email addresses that are known to belong to either a mailing list or spam detection service.
Import limits on role-based addresses
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.
Add attachments to an email invitation
While you cannot attach a file to an email directly, you can import this file in your media library and then link to it from your email.
High bounce rate warning
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.
Which IP ranges do I use to whitelist CheckMarket emails?
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.
Add a survey to your email signature
By adding a survey to your email signature you can get a higher response rate, without much additional effort. Simply respond to those emails in your inbox!
How to embed a survey question in an email
With the CheckMarket survey tool it’s possible to embed a survey question in an email. The embedded question should be a ‘single-select’ question type.
Send email invitations via CheckMarket
You can easily send your survey email invitations via CheckMarket. The tool will keep track of who has already answered, who needs to be reminded, etc.
Embed the NPS question in the survey email invitation
You can embed the NPS question directly in a survey email invitation. The selected score will automatically be registered as a survey response.
Domains used in surveys
Here are a list of CheckMarket domains used in surveys. Make sure all of them are reachable if your respondents have limited internet access.
Send preview email invitation
Send an example of the email invitation to yourself or a colleague or preview it in your browser before sending the invitation to your contacts.
Reset survey contacts
Resetting contacts makes it possible for those contacts to fill out the survey again using the same link that they have received before.
Download the unique hyperlinks for your contacts
You can generate unique hyperlinks per respondent and link survey answers to the respondents. You can also monitor who has already filled out your survey.
Email batches and drip surveys
When you send survey invitations, you can set up email batches so your invitations are sent out spread out over time. This is also called drip surveys.
I want to send a large number of emails to the same domain. What should I do?
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.
Set up a soft launch
A soft launch means you gradually send out email invitations for a survey so that any teething issues can be addressed before the entire panel is invited.
Send invitations with your own email platform
When using email as a distribution option for your survey, you can choose to send your invitations with your own email client.
What is my contact’s personal survey link?
When using contacts, each contact will receive a personalized survey URL. If a contact loses their personal survey link you can easily retrieve it.
Expiration date for a group of contacts
Adding an expiration date to survey contacts comes in handy for long-running or continuous surveys. After this date they can’t access the survey anymore.
Invitation date for a group of contacts
You can set an invitation date for your survey so your contacts receive the invitation at a certain date and time decided by you.
Bounce types and bounce subtypes
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.
Own domain for surveys & reports
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.
Sending automatic reminders
You can send two different types of reminders for your survey. Each type is sent at a different time that you can decide yourself.
Unsubscribe (opt out) contacts
Contacts can be unsubscribed from CheckMarket surveys in two ways: via the opt out link in the e-mails or you unsubscribe them yourself via your account.
Tips when sending reminders
Composing a good reminder is crucial to the success the reminder will have. As with the invitation, the subject line, the text and the design of the reminder will determine the click-through rate (How many contacts followed the link in the reminder to the survey).
Contact statuses
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.
