When you send out an email, it goes through a series of SPAM-filtering tests that determine whether it will be let through to the inbox.
And sure, this doesn’t really stand in the way of your email getting through when you want to just grab a coffee with friends (unless there’s 500 of them and you’re emailing them all at once with the same message), but it might prove problematic when you’re reaching out to prospects or clients and your messages keep being mistaken for SPAM.
See how to make sure your emails are getting exactly where you want them to – to the contact’s main inbox.
Why are your emails falling into SPAM?
You may do everything by the numbers, and still have your emails diverted from their intended destination into a SPAM folder. Why is that? There’s a bunch of possible reasons.
Before we take a closer look at them, we need to take a short detour and see how SPAM filters work first – the better you know this, the less likely your messages are to go into SPAM.
How do SPAM filters work?
The first thing you need to know may be basic, but I’ll put it here, just to make sure you know it: there isn’t one general SPAM filter that guards each and every mailbox on the Internet.
Each email provider may be using a different set. They all play the same role, though: to protect us, the email service users, from malicious content and cyber attacks. And help us keep our inboxes uncluttered.
They do so by filtering the emails, checking for common SPAM factors.
When deciding whether an email will go through or not, mailbox providers typically verify:
- If you (the sender) are allowed to use the domain you’re sending from and if the message wasn’t opened on its way to the recipient;
- The email copy, looking for words commonly used by spammers;
- Whether your email address or domain have been blacklisted;
- How many links did you put in your email and whether they direct to suspicious websites;
- Engagement rate (based on emails you’ve sent previously)
SPAM filters use a variety of techniques to assess these criteria, for example: header analysis, Bayesian algorithms, blacklisting and whitelisting, heuristics filtering, keyword matching – just to name a few.
Each of the techniques assigns a score to the email. If the total score adds up above a certain number, the message is tagged as spam and gets diverted to the recipient’s spam folder, or is rejected and bounces.
The filters use algorithms, which aren’t always 100% accurate, so the tests can at times result in false positives (legitimate email mistaken for SPAM) or false negatives (SPAM mistaken for a legitimate email). That’s why it’s important you know what can trigger the filters – this way you’ll know how to avoid getting into SPAM.
Now, let’s get to the point: what can you do to never have your emails diverted to SPAM again?

How to Avoid the SPAM Folder?
You can avoid the SPAM folder by following these guidelines:
- Take care of technical settings
- Check your email for SPAM-triggering words
- Diversify the content of your emails
- Don’t send all the emails at once
1. Take care of technical settings
One of the possible reasons why your emails are getting into your recipients’ SPAM folders instead of their main inboxes is that you haven’t set up your SPF and DKIM records. If you’re not familiar with what those are, let me explain it just real quick.
SPF (Sender Policy Framework) serves as a verification system — it determines which IP addresses are allowed to send emails on behalf of a domain. The IPs are stored in the DNS (Domain Name System) record.
SPF has been created to prevent internet villains from tricking people into thinking they’re the real owner of a domain. When a new email tries to get to a mailbox, the mailbox provider’s system accesses the DNS record to check if the IP is assigned to the domain.
DKIM (DomainKeys Identified Mail) works the same way. It has to do with encrypting your signature with a unique private key, which can then be decrypted by the recipient of your message. It’s an additional stamp of approval. Setting up your DKIM may be a bit tricky, but it’s a must-do.

Once you’ve got this out of the way, you can move on to the content of your message. Let’s take a closer look at your email copy.
2. Check your email for SPAM-triggering words
Your messages won’t fall into the recipient’s SPAM folder if you send a quotation using the dollar symbol or congratulate your addressee on their book being published (even though both “$” and the word “congratulations” are SPAM-triggering words). But if you do that for a bunch of prospects and add a couple more such words, your emails may go into the addressees’ SPAM folders without you even realizing it.
After you compose the email copy, it’s essential that you check it against a list of SPAM-triggering words. If you find your copy to be full of these, rephrase it, just to be sure that you won’t be taken for a spammer.
Also, be careful if you want to add any links to your messages.
3. Diversify the content of your emails
If you send a batch of emails with exactly the same content (even if there’s not a single SPAM-triggering word in your copy), your emails may not go through to the recipient’s main folder. Why? Because sending the same message to as many recipients as possible has been one of the spammers’ tactics for a while now, so email providers learned to recognize it as such, and might divert your messages.
That’s why it’s important to use custom fields in your cold outreach emails. This way, you can send messages at scale, yet diversify their content, which makes the SPAM filters see you as a valid sender and allow your emails to reach their intended destination.
Another way to make your campaign content diversified is to set up conditions to your messages: if a contact fulfills it, they’ll get version A of the follow-up message, and if they don’t – they’ll get version B.
This way you can not only raise the engagement of your campaign, but further personalize and diversify its content.
4. Don’t send all emails at once
Don’t send your messages all at once — that’s a typical spammer behavior, and as such will make you look suspicious in your recipients’ email providers’ eyes. Instead, let the emails go out in a steady flow within a wide enough sending time frame. You don’t want any peaks.
If you have a high volume of contacts that you’d like to reach out to, divide them into smaller segments and set separate campaigns.
Aim at a sending time frame that will resemble manual email sending. Usually, you’d probably need about 60 seconds to send an email. Try to mimic this in the automation tool you’re using. This way you’ll significantly lower the risk of your emails getting to SPAM folders.
To sum up… How to get through SPAM filters?
- set up SPF and DKIM
- check email copy for SPAM-triggering words
- use snippets and conditional emails to customize & diversify
- check email copy for links: how many are there & where do they divert to?
- set a wide enough sending time frame to create a steady email flow
- bonus – if in doubt, segment your prospects and start with small campaigns to test the waters first
SPAM filters do a great job protecting us all from internet bad guys, but their algorithms aren’t always accurate. That’s why your emails may end up in a SPAM folder even if you know you’ve done nothing spammy at all. But no worries – follow the advice I shared in this article and you should be just fine.
