How to send bulk emails without getting blacklisted
One of the main reasons why it is more and more hard for email marketers to avoid their campaigns being blacklisted is that spam filters toughen the requirements for filtering SPAM. That is why you can see the low open rates in your email campaign statistics – some of the newsletters were flagged by spam filters.
The Return Path Deliverability Benchmark Report based on the analysis of 2 billion promotional email messages runs that “globally, one in five message does not reach the inbox” and shows that 6% of all sent emails were delivered into junk folder.
It’s a rather great percent, isn’t it? Yeah, the spam filters are not absolutely accurate and even valid newsletters can go to spam. Here we are going to tell you some tips how to send bulk emails without spamming.
Reasons why your emails going to spam and how to avoid this
- You haven’t got a permission to send newsletters to your clients
Advice: Pay much attention to subscriber engagement. Your email marketing should be a permission-based marketing. Place the opt-in form to your website to get the clients consent before sending them any email.
- Your mailing list contains bad email addresses
Advice: Verify the mailing list regularly to detect and delete nonexistent and invalid emails with the help of email verification services. Otherwise, here is the risk for your domain or IP address to be penalized by your email service provider.
- You have low open rate and you are not the sender to trust
Advice: Never send spammy newsletters, ask subscribers to add your address to their contact lists. Almost every ESP has a list of approved senders. When your email messages are read, when people show that they trust you as a sender you have a chance to go into inbox always.
The one more reason of the low open rate may be the rare and irregular sending campaigns. If so, subscribers can just forget you, your company, the reason they’ve subscribed and mark email as spam. Work out a marketing strategy and keep up the sending plan.
- Your IP address is blacklisted because it was used for spamming (even if it wasn’t you who sent spam)
Advice: Choose a reputable email service provider, because they monitor and control IP addresses their clients use.
- There isn’t an unsubscribe link in your email message
Advice: Create and place a noticeable unsubscribe link.
Make a clear way to unsubscribe in one or two clicks. Do not be afraid of losing readers – it’s better for your sender reputation if they opt out of the newsletter than mark it as spam.
Are you interested in the reasons they unsubscribe? Create a special unsubscribe page.
Such kind of page includes a form the client fill in with the explanation of why he decided to leave and unsubscribe. Moreover, the unsubscribe link absence at once indicates the email as a spammy one.
- You’re using untrustworthy links
Advice: Never use a generic short URL (like short.ly/24u93jf) in your newsletters, as they’re renowned for being associated with spam. Email clients will often filter out and block any emails or newsletters containing these types of links because they could be masking malicious content, and the chances of the domains being blacklisted are very high. Instead, you should consider using a branded URL shortener that enables you to create links with a custom domain that you own (like YourBrand.is/Better), meaning your links aren’t at risk of being blocked and your newsletter deliverability rate will skyrocket.
- Your email is all one big image
Advice: Create an HTML template that includes both types of contents – text and images. Do not use large background images. Spam filters easily detect image-based newsletters and ‘kill them with no regret’.
- Email message template contains bad html code
Advice: Use a professional ready-made templates or a special html coder. Some of email service providers have WYSIWYG editor that helps user to make an email template himself.
- Email content contains spam words
Advice: Avoid ALL CAPSLOCK and too much colored fonts; do not use spam-like text. You can analyze your own spam folder, find out the mistakes and avoid them in your campaigns. There is software that allows checking email message for spam before sending. Such kind of check is made with the help of Spam Assassin tools and shows you the total spam score.
Moreover, you can see the list of mistakes you’ve done while preparing the email campaign, and the advices how to improve email message.
- You do not test emails before sending
Advice: Send spam email test! We recommend you to create accounts on different email services like Gmail, Hotmail, Yahoo, etc., and send the email message to them first. Check if the message goes to inbox folder, check if images display correctly in different browsers and on mobile phone.
Prepare a web-version of your email if necessary.
- You send boring newsletters
Advice: Take care of your subscribers. Offer them only valuable and relevant content. Try yourself with re-engaging the inactive readers. Make a marketing plan, mind the holidays and events, personal birthdays (if you collect such information). Be interesting for people.
