Spam filters are an excellent way to keep unwanted emails from blocking your inbox. They use advanced software programs that can detect malicious phrases and words, so they can prevent harmful communications before they even arrive at you. In other terms, spam filters help safeguard us in the digital realm – keeping our data safe!
Initially, the Internet provider eliminates junk email by filtering out messages from blacklisted IP addresses. Then, to ensure further protection of their users and keep them safe from unwanted content, mail services analyze emails with advanced filters. Furthermore, for added defense against commercial networks and for blocking marketing campaigns directed at corporate employees' emails - companies may have an additional corporate spam filter installed.
Lastly, emails are filtered through individual configurations that have been set up by the receiver themselves in their mailbox or application settings. These user settings remain valid for each account separately.
Protecting your mailbox from the ever-growing number of unwanted junk emails is essential to avoiding frustration and safeguarding yourself against scammers’ malicious links. Not only do spam filters protect your mail, but they also safeguard confidential data, trade secrets, and even money stored on your computer. Successful email marketing is impossible without good spam filters.
All spam filters can be divided into two types:
1. Automatic - which is fully controlled by the system.
2. Non-automatic - those that the user configures himself. For example, the user can set up a list of spam words based on which emails will be identified as spam messages.
Almost all modern spam filters use artificial intelligence in their work.
For example, Google has been using AI since 2015, the company already claims to be able to block 99.9% of spam from reaching inboxes while misclassifying legitimate email as spam only 0.05% of the time.
Filters are self-learning and ever-evolving. They observe the status of a sender's domain, authenticate it to confirm its legitimacy, then review both the message content and how recipients interact with it. In this way they can ensure that only quality emails make their way through.
1. Analysis of the reputation of the IP address and domain.
If you are added to the DNS Block List, your emails will be blocked due to spam filters that access blacklists of IP addresses and domains. Don't let this happen; make sure you're taking all necessary precautions against spammers!
If you want to ensure the reliability of your IP address and emails, checking blacklists manually is time consuming and tedious. Luckily, Warmy provides an easy solution! Simply input your data into their system and in minutes it will let you know if any of them are on a blacklist. This speedy process helps prevent embarrassing email bounces or blocked communications due to being flagged as spam. Don’t waste another minute - use Warmy now for fast results that keep your communication running smoothly!
If your domain is new, you'll likely encounter difficulty with email spam filters since there isn't yet any established credibility. As a result, Warmy strongly recommends warming up these domains by slowly increasing the mailing volume. This gradual approach will help build up trust and ensure that emails from this domain are treated properly by subscribers.
2. Checking the settings of authentication protocols.
Authentication is a process of verifying the identity of message originators. Emails that fail authentication are blocked as suspicious or spam. Three primary methods for email authentication exist - DKIM, SPF, and DMARC.
A DKIM signature verifies that emails come from approved domain owners, while SPF blocks messages from originating addresses outside its record list. Last but not least, DMARC safeguards domains against malicious attempts to spoof them with fake sender identities in an email address field

3. Content and format
It's essential to experiment with various approaches when creating emails, so be sure to A/B test emails. The spam filter examines the presence of any potential spam words, whether a sender is present or not, how many recipients there are, if attachments and links exist (as well as their sizes), pictures included in the email—the list goes on.
Unfortunately for those who don't pass this verification process; their messages will automatically go straight into that dreaded Spam folder! To guarantee your message reaches its destination without fail why not use our convenient free Email Template Checker?
It is very easy to do this, just follow the link - Email template checker and paste your text into the window, and the system will automatically detect errors that can lead your email to the spam folder.
4. Checking the Subject of Your Emails
Crafting the proper email title is an art form that requires precision. If you fail to carefully craft your titles and include spam words or excessive capitalization, your emails could end up in the dreaded abyss of a recipient's spam folder. To avoid this fate, A/B testing will be absolutely crucial for getting your messages seen!

5. User engagement analysis
The reaction of your subscribers to your emails is an absolutely vital metric. If people don't take the time to read and delete it, mark it as spam or complain about you, then naturally their confidence in your mailing list will decrease. On the other hand, if they open up the email, click on any links inside it, reply back or forward while also marking "This is not spam", then that means a great deal for building up their reputation with those recipients.

To maintain an organized and clean inbox, it is recommended to have separate mailboxes for various types of emails (ads, transactions, business-related messages).

This action will keep the primary address from potential issues that may arise.
