How to send bulk email without getting blacklisted?

The following points will discuss certain practices and modifications needed to make the email land in the inbox. 

1. Making use of double opt-in

By making use of double opt-in, the email list won’t suffer bounces. This is because the users will be asked to verify their addresses by clicking on a verification link that will be unique for each person. No doubt, this verification link will reach their inbox. 

By creating an engaged list of the users, you are sure that the subscribers are interested and looking forward to receiving your emails. Else, they won’t have followed those two steps and the verification process. Thus, the engagement rate will get accelerated owing to the greater frequencies of people clicking the link sent by you. As a result, the spam filters will get a positive signal and won’t make your emails delivered in the spam box. 

2. Prepare the email list from the very beginning and avoid procuring it externally

If you obtain or purchase an email list from the internet or outside source and send emails to those addresses, your mails will out rightly be branded as spam by the filters. This is because those people never subscribed to receive those emails. Moreover, as mentioned by the CAN-SPAM laws, sending unsolicited emails may make you go through legal proceedings. Anyways, those people who had never shown interest in receiving your emails will mark your messages as spam. This will send a negative signal to the spam filters. So next time, even if you send solicited emails, your legitimate mails will also end up in the spam folder automatically. Prepare the email list after making people interested in your content and providing them with enough reasons to show why they should start receiving your emails. 

3. Cleaning the email list

You must delete the incorrect and not-so-important data from the email database to keep the email list precise and clean. For instance, you can set the period of 90 to 180 days as the time for email washing. This implies that you can remove those email addresses that have not responded to your emails in the past 90 to 180 days. 

Before cleaning up the list, you can send the last mail to those users informing them that you’re cleaning up the email list and wanted to know if they are still interested in receiving your mails. If not, you may ask them politely to unsubscribe from your emails. If your list contains all the valid data, it ensures a good engagement and high chances of the mail reaching the inbox. 

4. Don’t send emails with only images as the content

It’s known to all how easy it gets when you have got to send only images as the website’s content. So if you are using this technique, stop doing this right now. This is because you’re only increasing the chances of your mail getting dropped in the spam box. 

It is the habit of spammers to use image-only emails. When you, too, start displaying traits of the spammers, the filters will mark your mail as spam, and it won’t make it to the receiver’s inbox folder. 

5. The authenticity of the emails

Making use of email authenticity systems is vital to maintain a relationship of trust with the mailbox providers. The more the messages pass the checks of authenticity, the greater are the chances of the emails getting delivered to the inbox. To get the mails to pass the authenticity check, some criteria are needed to be fulfilled. 


Following the procedures mentioned above will likely result in the mails getting delivered to the inbox. Avoid getting negative engagement and having a lousy email design to avoid the mails from getting dropped in the spam box.
