When you send a cold email, you need your message to resonate with the reader. It’s important to have a strong message. However, it’s even more important to have a quality spam checker to deliver it properly.
How you compose your email template, your copy and your images play an immense role in the effectiveness of your email campaign.
Both of these come into account for cold email campaigns. Not only is it important to convince the reader to take the action you’re encouraging, but you also need to convince spam filters that your email isn’t spam.
When you send a cold email, your internet service provider (ISP) analyzes your email to determine whether it should make it past the server, land in the inbox or be categorized in a ‘spam’ or ‘promotions’ folder.
It takes a wide range of factors into account. Some of these may include how many emails are being sent and received by your sending IPs and domains. This could also include the engagement rates of your emails (as in how many people open or click your emails), which words and phrases are found in your copy, and whether your IP or domain is on a blacklist.
ISPs & Sender Scores
ISPs assign a “sender score” to each IP address and domain you send from, based on the above criteria, which is what tells them how likely your emails are to be legitimate.
Once your campaign makes it past these checks, it must go through the same process at the recipients’ end, through their mail client.
If you want your cold email campaigns to succeed, your content needs to be stellar and relevant to the reader. The more your email contacts engage with your message the more acceptable the message will be received by spam filters.
So, what happens when your email gets flagged as spam? Well, you can expect to experience a strong drop in deliverability. As a result of that, it is likely your campaigns will end up in a spam folder and unseen by your recipient.
Even worse, your sending IP and domain may end up blacklisted. This is widely considered a death sentence for your future email campaigns.

How to Avoid Getting Blacklisted
If you want to continue delivering cold email campaigns, you need to ensure you remain off blacklists. Should you happen to land on one, it doesn’t matter how great and relevant your message is as the likelihood of your intended recipient seeing it is low.
What’s the quickest way to get on a blacklist? People reporting your email as spam. You want to avoid this at all costs by creating relevant, engaging content. By knowing who your target audience is and then crafting your messages specifically for them is the best option to increase your engagement rate.
An often-overlooked method to avoid blacklisting is to ensure you have an unsubscribe option in all your emails. Not only is this mandatory for remaining CAN-SPAM compliant, but recipients may report your message as spam if you do not. Best bet: include a readily-apparent, functional unsubscribe link in your emails.
Sender Status and Deliverability
Running your contact list through an email verifier is an extremely important step in keeping your deliverability maximized. You need your email list to be clean of bad data and spam traps, too.
For example, if you’re hitting a high number of spam traps and hard-bouncing off bad addresses, it indicates that you’re not being careful about who’s on your contact list. This is a major indicator that you might be spamming.
Another major red flag is whether your email content looks like typical spam. There’s a wide range of phrases and formatting that spammers tend to use, and if you’re using them too, that sends a red flag to spam filters.
Every mail client that is sent an email has a different (and ever-evolving) list of what constitutes signs of spam. It can be very difficult to create content that completely avoids setting off red flags. Here are some common examples:
- Wording such as “free”, “try now”, “limited time offer” are often used in spam messages.
- Formatting with all caps, multiple fonts and text sizes, and multiple text colors.
- Links that point to a different page than the one the text indicates.
- Large images and little text content.
It’s impossible to keep everything in mind when creating email content. This is where a spam checker comes into play and can be extremely handy.
