Plain text email vs “fancy” HTML email
When sending email campaigns you have the option of composing your emails as HTML or plain text. With HTML you can have fancy formatting, embedded images, etc. With plain text emails you just have text. There are pros and cons to each format. I am a proponent of sending plain text emails, but rather than explain the reasons behind this preference, I’ll send you over to a great article written by Aaraon Traffas at his blog on AuctioneerTech.com:
Sending plain text email is better for users and branding
Aaron makes some very good points in his article and hopefully convinced you of the merits of plain text email over HTML email.
