What is an email campaign
An email campaign (email blast) is one message, or a short series, sent to many people on a list at the same time: a newsletter, a promotion or a survey invitation. It goes out through an email service that handles the list, unsubscribes and delivery reports.
A campaign should go only to people who agreed to get your emails, and each message needs an unsubscribe link. Campaigns are measured by delivery, opens, clicks and unsubscribes. For a survey invitation, the number that matters is the response rate: how many recipients finished the survey.
How it works in SurveyNinja
SurveyNinja doesn't send email campaigns. Send the invitation from your email service or CRM, and use SurveyNinja to see who responded:
- Unique links (Standard and higher). A separate link for each person or group, up to 1,000 at a time, with names if you add them. Each response shows which link it came from, and a single-use link accepts one response.
- Hidden variables (Basic and higher). Add parameters such as the campaign name or a customer ID to the link, and the values arrive with each response.
- Emails after the survey. SurveyNinja can send the respondent a thank-you email and you an email notification about each response.

Tips for survey invitations
- Put the reason and the survey length in the first lines of the email.
- Use one clear button that opens the survey.
- Send one reminder to people who haven't answered. Unique links show who they are.
