Remember, that technically incorrect emails are often identified as spam.
HTML source code is another important moment. Never use applications that create
awful HTML code. If your message has too complicated structure, or contains
empty or invalid tags, email servers may regard such emails as spam. Try not to
overload your message with illegible fonts, bright backgrounds, or other
elements that will distract the readers' attention.
Make the layout of your email as simple as possible. Keep in mind that your
newsletters should be informative. The information you share has more value than
the outlook of your message. The outlook should be simple and function. So, try
to avoid complex formatting.
You will considerably increase the deliverability, if about 80% of your
message is text. Try to substitute picture buttons with HTML. Don't include
ActiveX. The less graphic you employ the better will be the results.

automated process which allows sending unique messages to every recipient. If
your mailing list contains various data, such as first name, last name, company
name, tile, country, etc, you can add all these fields into your message.
Never mislead your recipients by writing deceptive subject lines. The subject
line should reflect the content of the message. It's a bad idea to include a
note that your message is not spam.
It is advisable to use normal conversational language. There's no need to use
redundant spacing, capitalization, or uncommon spelling or characters.
HTML vs Plain text
There's no need to give preference either to messages created in HTML-editors
or plain text. Instead, it is advisable to include a plain text version in
addition to your HTML email. Plain text version is necessary mainly for
anti-spam filters rather than for your recipients. It will give you a guarantee
that your messages won't be regarded as spam. Bulk Mailer creates plain text
version by default, no matter whether you've created the message in Bulk
Mailer's editor or imported the template from the file.
Disable Scanning of Outgoing Emails

Bulk Mailer works via direct and relay sending modes.
Direct sending mode
is the default mode. It works as a built-in SMTP server. It is of utmost
importance to have access to 25 port. If it is blocked by your ISP, you won't be
able to send messages via direct sending mode, only via relay mode.
sending mode uses your ISP's SMTP (or any other you specify). Every ISP has its
own limits on the number of messages sent. Please, contact your ISP to find out
if there is such limit. If the limit is 200 messages per day, the program will
fail to send 5000 messages via relay sending mode.
If you don't have a
possibility to use direct mode or your ISP's SMTP, you can use one of the
Order shared hosting account (it always comes with SMTP server
access). Pay attention to number of messages allowed per day. ·

server. If you're using unreliable SMTP, the rate of undeliverable mails will be
much higher. A good SMTP guarantees a high speed of sending and delivery rate.
