1. Size of the Html emails:
Size does matters. If the emails are bulky, spam filters think they
are spam. So they will be deleted or directed to junk folder. Better
be less than 20 kb.
To make Html emails with small sizes follow these principles-
Do not use WYSIWYG editors to create Html emails.
Do not attach images to messages. Upload the images to your website
and link from there.
Mind attachements that you will send with emails.
They potentially decrease the deliverability of your email in to
your subscribers inboxes, because people disables these in their email
clients to run.
3. Html complexity:
Most of the email clients support only minimal html. Like simple
break tags, paragraph tags etc. Do not use complex html code like
frames, sliding menus etc.
4. Hiding and Tracking links:
Great advantage of Html emails is you can hide your affiliate links
and track who opened the emails (only if images are downloable).
5. Easy to publish on the web:
Make a template for your Html emails. So let all emails be consistent in
layout. You can publish the ezines or ecourses on the web directly from Html
emails. You do not have to format like in text emails.
All mailing list managers has the ability to attach single or
multiple attachments. But spam filters triggered by attacments in
many email clients. So put them as download links.
7. Links in Html emails:
Try not to misdirect your subscribers. Best way linking is by using
legit wording. Like if you are keeping the following affiliate link
(example – Http://www.affiliatesite.com/affiliate.php?idxxxx ) for a Suche engine
optimization ebook, keep this url linked to the word
'Search engine optimization strategies guide'. Do not link to affiliatesite.com
This way subscribers know what they are clicking and what to expect
8. Email clients limitations:
Not all email clients display Html emails properly. So offer a choice
for your subscriber to opt for text emails in your email letters.
