How To To Avoid The Spam Filter During Your Email Outreach

Do you know what makes an email bounce?

How are you going to make sure that YOUR emails reach your prospect’s email inbox?

In this article I’ll tell you about some of the best things you can do to keep your message away from spam filters.

#1. Use Valid Email Addresses

As I’m sure you know, if you try to send a message to an address that doesn’t exist, your email will bounce. This can seem like a no-brainer, but there’s another reason why this matters.

If you send too many emails to invalid addresses, your entire DOMAIN can be blacklisted by servers across the web. This means that other email accounts at your domain (your co-workers or even your boss) could have their emails flagged as spam because of messages that you sent.

You can use a tool like MxToolbox to check if your domain has been blacklisted.

#2. Remove Images or Use Sparingly

I know how hard it can be to catch and keep the attention of your prospects. Some of these people probably get dozens or even hundreds of outreach emails each day – how can you stand out?

My recommendation would be this: reduce the urge to use eye catching images – at least in your initial outreach. Images from unknown senders (read: YOU) can be instantly blocked by corporate email filters, and can even cause your email to be trashed without a second thought.

Even in your email signature, it’s best to use text only until you’ve established a relationship with your prospect.

#3. Check Your Tracking Links

Consider the following formats:

The first option is called a naked link, and the second option is called a masked link. The URL in the second option is “masked” by the text, hidden behind the anchor text.

You may be tempted to write out the URL to your website as a naked link, but beware! If you’re using any kind of email tracking software, the link to your website will often be replaced with a complicated tracking link.

If the corporate email filters sense a mismatch between what you SAY the link is ( and what the actual URL behind the text is (, this can be a red flag that causes your email to be flagged as spam.

When you’re using links in your email, make sure to mask them with text. Don’t write out the URL unless you don’t plan to use click tracking software.
