As you know, Auto Mail Sender provides the plain text and rich text email format, and some other email clients provide this also, such as Thunderbird, Outlook, Outlook Express, Windows Mail and Foxmail.
How to correctly select the email format? Let us see the comparison of plain text and rich text first.
The features / limitations of plain text: 1.
Simple and easy, only needs typing and typing.
2.
It is small in size, only includes the texts which you typed.
3.
Inner links are readable for the common email clients.
4.
It is not easy to be treated as junk email.
5.
Does not support individualized texts, colors, images, sounds and videos in the email content.
The features / limitations of rich text: 1′.
Complex, except typing and typing, you need to click a few menu items or buttons to compose your email content.
2′.
It includes some additional HTML tags and properties, it is larger than you want to express things.
3′.
Inner links are readable for all the email clients.
4′.
It is easy to be treated as junk email if you quoted many external resources.
5′.
Supports individualized texts, colors, images, sounds and videos in the email content.
Refer to this comparison: We suggest you choose plain text if you do not need to send images, sounds and videos in the email content, because plain text is simple, easy, small (fast) and safe.
Only when the plain format does not meet your needs, you should use the rich text only, because rich text is complex, large (slow) and unsafe.
Some times, the rich text is not a rigid demand, for example, you can put the content images as the email attachments to make the plain email.
Now, you should know why Auto Mail Sender set plain text as the default value for email format.
In fact, this experience is effective for any other email clients, not only for Auto Mail Sender.
