              The ideal shipping moment depends on the target audience and the periothe. Our advisers will be happy to help you with appropriate advice. Send a message to campagne@duo-onderwijs.nl or Call our advisers on +31 30 263 10 88. 

              I want to submit an HTML file. How do I do that?

              We would then like to receive via campagne@duo-onderwijs.nl an HTML code. Here, it is important that the data in the mail does not need to be modified, as we can no longer make changes when we receive an HTML file.  

              Not sure how to get an html file? Here are two easy ways to create an html file: 

              Export or copy from mail software: Most mailing software allows you to export or copy an HTML code. Then open a text editor on your computer (such as Notepad, Notepad or TextEdit), paste the HTML code into it and save it as an .html file. Remember to end the file name with .html (for example: newsletter.html). 

              Open e-mail in the browser: Send the e-mail to yourself and open it. Look for options such as “View in web browser” or “View online” (usually at the top of a newsletter). Click on it to open the e-mail in the web browser. Then right-click on the page, choose “Show page source” or “View source code”, and copy any HTML code that appears. Paste this into a text editor and save it as an .html file.  

              I would like you to format the mail. What is the procedure for this?

              You can! We are happy to receive the desired text and images via campagne@duo-onderwijs.nl. Do you also want specific colours or use fonts? Send these along too, so we can incorporate them. View the delivery specifications

              Can I see afterwards how the DM performed?

              Yes, that is possible! After sending the DM, we will send you a report. This shows you the reach of the DM and relevant information, such as the number of opens and clicks. 

              What is an A/B test?

              An A/B test in email marketing is a way of discovering which version of an email works better.

              How does it work?
              You create two variants of one e-mail (A and B). Only one element differs, for example: subject line/sender name/call-to-action. We send version A to a small part of the target audience and version B to another small part.
              Then we compare the results, such as: open rate, click rate or the conversions. Based on these results, we choose the mail that performed best. We send this to the remaining large part of the target group for optimal reception!

              What is a reminder email?

              A reminder email is an email to people who your previous DM have not opened.

              We send the first DM and after a few working days we select the recipients who have not opened the mail. That group gets the same mail again, so you reach the target group in the best possible way.
