Email requirements

Campaigns with emails

Campaigns may be followed up by two emails from the partner:

  • Confirmation email: an initial, one-off, immediate send to end users that confirm a customer has accepted a specific offer on the Rokt platform, with coupon details (if applicable).
  • Reminder email: a second email reminding the customer to use the offer they opted into.

Best practices

  • Keep a good text to image ratio: Do not send emails with just an image in the body but no other content. Include at least several lines of text with each image.
  • Optimize images: Use a maximum size of 150KB and add alt-text in your HTML file so there is fallback text if the image does not appear.
  • Send valuable content: Ensure emails are relevant to your campaign.
  • Fonts: Use fonts like Arial, Verdana, Georgia, or Times New Roman that work across all email platforms, or make sure fallback fonts are specified in the code.
  • Optimize for mobile: Ensure emails are legible and load quickly on mobile devices, and that links can be pressed easily from a mobile device. Increase button size with CSS if necessary and keep links above the fold.
  • HTML code best practices: Keep your HTML code as simple and clean as possible, and use a maximum body width of 700 pixels. Having a proper CSS section allows your email to render properly on mobile.
  • Do not use spam triggers and phishing phrases such as "Will not believe your eyes, Satisfaction guaranteed, Compare rates", etc.
  • Email format and content: Avoid overuse of capital letters and exclamation marks. Use a variety of font sizes, styles, and colors.
  • Do not abuse text-based emails: Text-based emails should be used sparingly as performance deteriorates over time.
  • Use HTTPs protocol: All hyperlinks need to be in HTTPs protocol.
