Best practices and guidelines
Separate the message layout into 5 pieces

- Logo/Picture Section (max. size 150 KB),
– Hint: use a message text container, not an image, if you want to have a possibility to change / delete image during your sample invitation process.
– An image in a text area uses the original size so upload the image to the library in the correct size. - Survey introduction and context:
– Reason for invitation
– Context about the survey
– Estimated duration - Invitation conclusion:
– Include the link to the survey
– Acknowlegdments for participation
– Contact details for questions
Duplicate the Default Invitation as a starting point for additional Message Layouts
We recommend to duplicate your existing Message Layout and edit it from there instead of starting from scratch by creating a completely new Message Layout:

This will ensure that you can always refer back to the original and will save you time.
Do not create the actual invitation in the Message Layout Editor
The Message Layout Editor is the overarching framework for the actual messages that you will create to invite your desired audience. This means that you should not write the actual invitation texts in the Message Layout Editor. The goal is always to maintain a low number of Message Layouts on which you base your messages.
This will help you to:
1. Preserve uniformity accross your messaging
2. Easily work with messages is several languages
3. Maintain a clear overview and structure
Stick to the standard settings
The Message Layout Editor allows elaborate options for customization, however all standard settings have been thoroughly tested to match the industry standards and ensure high email deliverability. The more you deviate from industry standards, the higher the chances are that the invitations will not reach your desired audience.
