    Once you’ve created a signature here, it will be available for you to choose from when creating a new email from that account. 

    Apple Mail users can use HubSpot’s Email Signature Generator to create customized, professional email signatures to copy and paste into their signature settings.

Optional signature formatting in Apple Mail

In the signature creator of Apple Mail, you’ll see two checkboxes.

The first says ‘Always match my default message font’. 

Check this box if you want your email signature to match the default font style and size you use for emails. Uncheck this box if you want to use custom formatting. 

The second checkbox says ‘Place signature above quoted text’. That tells Apple Mail where to put your signature on messages you reply to or forward. 

If you check the box, your signature will appear after the message that you typed above the original message. If you uncheck the box, your signature will appear at the bottom of the thread.

Automatically add your signature to Apple Mail emails

To automatically add a signature to every email, you can follow these steps. 

  1. Open the Mail app and navigate to ‘Mail,’ then ‘Preferences’.

    You can still change or remove signatures automatically added to your Apple Mail emails. To do this, use the ‘Signature’ dropdown menu in a new email and select ‘None’ to delete the signature, or choose a different signature to replace your default one.

How to add logos to email signatures in apple mail

One of the best features for Apple users is the Apple Mail image in signature functionality. You can easily use your Mac computer or laptop to add a logo to your email signature.

To add a logo to your Apple Mail signature: 

  1. Add an image file of your logo to your Mac desktop.
  2. Open the Mail app.
  3. Navigate to ‘Mail’ and then ‘Preferences’.
  4. Select ‘Signatures’.
  5. Drag and drop the image file from your desktop to the right column where you can edit your signature.

And that’s it! Your image will appear in your Apple Mail signature. (You can remove it by highlighting the image and hitting ‘delete’.)

If you’re using Apple Mail, you can create a professional email signature with HubSpot’s Email Signature Generator and paste it into your signature settings.

How to add HTML signatures to Apple Mail

Apple Mail doesn’t allow you to paste HTML code directly in the ‘Signatures’ pop-up menu. Instead, you’ll need to create a new signature and then find and edit the signature file on your Mac. 

You can find more detailed instructions about adding an HTML signature to Apple Mail here.

That being said, there’s an easier way to get a custom-formatted signature to Apple Mail using HubSpot’s Email Signature Generator.

To add your custom signature to Apple Mail after creating it on HubSpot:

  1. Copy your signature.
