Maildoso Deliverability Guide

Your sequence is your main deliverability enemy

Email providers pay special attention to the content of your email.

They are looking for red flags.

If your emails are suspicious, they won't land in the inbox.

This guide will teach you how to make your email land in inbox.

Keep in mind, that these tips are valuable regardless of what cold email infrastructure you use to send cold email: Google Workspace, Microsoft Outlook, or Maildoso.

Send text-only emails

Spam filters try to protect their users against phishing attempts and malware.

Text-only emails are the safest from that standpoint.

So more people will receive your email because it looks safe.

You won’t be able to track open rates though. But your replies will increase.

At least create a text-only copy of your campaign and test it.

Top 10% of maildoso customers use text-only mode for cold outreach.

Still a fan of tracking open rates?

Forget about it.

If your email contains an open tracker, Google will display this warning to its users.

As a result, you will start getting much more spam complaints.

Text-only campaigns perform much better.

Avoid using images and links in your first email

Unsubscribe link is okay, as long as custom domain tracking is enabled.

In other cases, it's better to replace it with unsubscribe text:

• “I will follow up with you in a few days. Let me know if you don’t want to.”
• “Reply 'not interested' if you want to opt-out from future emails”
• “Reply "not interested" if this is not relevant”
• “If you don't want to hear from me anymore, just let me know.”

🚨 Signature

You won't believe it, but this element of cold email causes the most deliverability issues.

Because even if you use a lot of spintax.

Some elements of your signature will be the same across all your emails.

For example, a phone number.

This is how it works.

An email provider receives spam complaints from 10 different people.

It spins up its machine learning algorithms to find what's common between all 10 emails.

Quite often it's a phone number.

So they start banning all emails from you that contain this specific phone number.

Try to keep your signature as simple as possible. 

Avoid adding:

• domains (NO DOMAINS IN THE SIGNATURE)
• links
• phone numbers
• license numbers
• no photo

Check for spam words

Make sure to have zero spam words according to this tool -> https://mailmeteor.com/spam-checker

Don’t forget to check your signature and unsubscribe text too!

Even just one word can hold you back from getting a solid 70% open rate.

Always have multiple campaigns running at the same time

At some point, email services will start banning some parts of your copy.

The greater variability you have, the better deliverability you can achieve.

You will notice, that after some time, one campaign will get 10% and another 80% open rate.

This indicates that the email provider blocked some words or sentences in the first campaign.

A good moment to put it on pause and create a new one.

Add as much SPINTAX as possible

The more spintax you have the better

Not enough of spintax

This is a healthy level of SPINTAX

Change campaign every couple of weeks

This is not a sit-and-forget type of game.

Your job is to outrun the algorithms of email providers if you want to have great deliverability.

This is certainly a game not for lazy people.

If you want to get tons of replies, update your campaigns regularly.

Add Unsubscribe Header

There are two main ways your prospects stopped recieving your followups.

1. Clicking Unsubscribe link
2. Replying to your Unsubscribe sentence

But what if you do not use either of them?

I personally found many email campaigns where there is NO Unsubscribe sentence / Unsubscribe link. Now it's against the GDPR compliance.

If you forget to add Unsubscribe sentence / link, Unsubscribe Header will be super useful to you.

This will not specifically improve your deliverability but Google and other big ESPs made this mandatory requirement.

Here's How you can add in Instantly

Go to Campaign option --> Show Advanced Settings --> Check Insert unsubscribe link header

Here's How you can add in Smartlead

Go to Campaign Setting --> At the Bottom of General Tab --> Check Add unsubscribe message in all emails to see Unsubscribe Header option.

How will it Look to your Prospect?
