A professional email signature can increase your response rate.
However, if you add the wrong type of signature, your emails could go to spam.
In this article, I show you how to write the perfect signature for your cold email campaigns.
I will cover the following:
I recommend that you use the below structure when creating your signature:
1st line: Name
2nd line: Position and company
3rd line: Location or address
I recommend that you keep your signature plain text (not html) as this will help with your deliverability.
If you send cold emails through Emailchaser, then your emails are sent as plain text by default.
Additionally, I recommend that you avoid adding images, links and phone numbers to your signature, as these have been correlated with emails landing in spam.
You can find this on the left side bar.
The settings section will open when you click.
Clicking this button allows you to write your signature.
Write your signature following the advice in this article.
Don't forget to click the save button.
When you are creating a campaign, you must add the {signature} custom variable to the signature box when writing your sequence. This {signature} custom variable will automatically add the signature details for each email account that you connect to your campaign.
I recommend that you don’t include links in your signature.
Adding links to your email (body or signature) can negatively impact your deliverability, meaning that your cold emails are more likely to go to spam.
I am not saying that just because you add a link to your email that it will go to spam. You might be ok adding a link or two.
However, in my opinion, it’s not worth the risk.
I recommend that you read my article Does Adding Links To A Cold Email Affect Deliverability? In this article, I discuss further how links can negatively affect your deliverability.
You should not include any images in your signature.
Images can negatively affect your deliverability, meaning that your cold emails are more likely to go to spam.
You can still set up a profile picture for your email account (which I recommend), but a profile picture is not the same thing as having an image in your signature.
I recommend that you don't add phone numbers to your signature because this may cause your emails to go to spam.
ESPs see a correlation between email accounts that include phone numbers in their signature, and these emails being sales-related, thus ESPs are more likely to send those emails to spam.
If you are scaling your cold email outreach, then you need to use secondary domains to create additional email accounts so that you can increase your sending volume.
The slightly confusing part of having secondary domains is that it makes you ask the question: "How do I create an email signature when each email account has a different persona?"
The answer is simple; all you need to do is add a signature to each individual email account (from the "Email accounts" page), and then add the signature custom variable to the signature box when you're creating your campaign.
This will automatically insert the correct signature for each email account that is connected to the campaign.
If you write your signature in the same format shown in this article, then you will increase your reply rate.
