Alongside the technical issues that can lead to your email to be blocked or filtering in other ways, there are other problems that could negatively impact the delivery of your emails. The issues we’ll analyze are related to your email content and are completely within your control. This makes it even more crucial to carefully review the content of your email newsletter prior to sending it out to your entire list of recipients to achieve the best delivery rate

Here’s what you should to pay close at when making and distributing your newsletter via email:

  1. Email Header

The header of your email is like a business card. In the event that you mail an email your email server is in dialogue with the recipient’s email server. The server transmits the message’s header to the recipient’s email server. If the server of the recipient is not happy with the way your header appears it won’t accept your email.

For example, if the “From” email address is “[email protected]” but the email server from which the message is sent is “” then the server supposes that the email header is forged.

Falsified headers for emails can be an issue since certain ISPs (in particularly, AOL) have stated they’ll remove email headers that are false and will pursue malicious senders.

  1. HTML Code

There’s no problem sending an email in HTML format. However, an incorrect HTML codes is one of the frequent cause for sending an email that is rejected. Simple mistakes in HTML could get you in problems with filters. HTML emails are often blocked by spam filters due to:

* There was no simple text format was supplied The recipient must to learn HTML

* No alternative text was added for graphics

HTML was either slipshod or improperly formatted

* HTML code contains dead links

* HTML code contains code that the ISP might consider to be harmful

To ensure your email doesn’t get affected by the wrong HTML code, you can use HTML validator tools to verify your HTML email prior to sending it out. If your email list includes large parts of email addresses from certain ISPs You can inquire with these ISPs whether they have any specifications for HTML.

  1. Content from Email

ISPs generally rely on a variety of variables to decide whether an email is either delivered or filtered. the message’s copy is among the factors which affect the ability to deliver. Copy is more crucial in the event that the ISP employs heuristics as an filtration criterion. There are certain words and phrases which can boost the score of an email that are not acceptable. The higher the score of the email the more likely it is to look like spam.

On the other hand You can’t make a decision without offering discounts, special offers or other kinds of promotions to encourage recipients into responding to the information in your email. Therefore, you frequently must use appealing for your recipients that they will think you are using spam words.

Be aware that copy in emails can affect the rate of delivery, so choose the words carefully. A one word or phrase that is not that is triggered by spam will not make your email appear to be removed, while other components of your email don’t boost the score.

  1. Email Blast Speed and Volume

This isn’t directly related to the content of emails, however we believe it’s crucial also. Spammers do not care about the volume of emails they send and speed of sending or even hygiene of their lists. Certain ISPs are attentive to the sender trying to send an enormous amount of emails to them. If they find any problems such as a large amount of emails that are not delivered, or complaints about spam the account will be removed at the request of an ISP.
