Email Marketing & Advertising Traffic
Very important point:
You should create a text email (text-only). Because one of the capabilities of mobile phones is the display of emails in the same way (text-only).
many users also activate this feature to reduce the use of Internet traffic and increase the speed of uploading. In this case, you also have to cope with this sub-standard.
Be careful about the size of the emails.
Emails ads services, like web pages and photos, have standards in their framing. Creating templates larger than this size makes emails look awful!
600 pixels seems to be the most ideal size for email templates. This size works well on desktop devices and tablets. But for mobiles, you can use the ability to automatically resize (using the if / then code) or use the standard size for mobiles. The width of the email traffic on mobile phones should be around 300 to 400 pixels. If you are not familiar with these items, you can take a few sample emails from different companies as a sample and check their dimensions and get an average and appropriate and standard size of their values.
It should be noted that with the new targeted email marketing & advertising traffic panels, you can automatically prepare responsive emails for any size (tablet, mobile).
