    How do you get a logo on the side of inline text? I’ve had it done by Fiverr and they never told me how it works. Great article!

  2. Wharf Xanadu says:

    Good to know how to do this. Always wondered if image could be better than a normal signature

  3. Carl Sutherland says:

    I have been trying to do this for at least an hour. I think some steps left out. Anytime I try to get image into this it is huge. Can’t find a way to get image anything like size I want it.

    • Run Buh says:

      Try making your image smaller (really small, no bigger than 300 pixels wide or tall) before inserting it into the email signature. As you’ve probably noticed, once the image has been pasted in, it can’t be resized.

    Using images, richt text and/or HTML in E-Mails is very bad style.

    Often those mails are displayed wrong. They produce useless amounts of data transfer volumes – think of mobile devices!

    And last but not least, they distract from the real content.

    Never ever use images in E-Mails!

  5. Simon says:

    When I paste my company logo image into the signature the image turns blurry. What am I doing wrong?

  6. Rachel says:

    Same here, image gets blurry and the size is tiny once sent. I did this for my colleagues, all are ok but one is doing the blurry and size think… :(

  7. Tony says:

    hi,
    well i tried the steps it works but, when i send an email to a Samsung device they cant see the image in my signature !
    how to embed the image in the signature so it shows on any mobile device ?

  8. Walter H says:

    As of the latest update, this no longer works. It displays as the filename, etc in the sig instead of the actual image.

    • Obtoi says:

      Recreate a new image signature, it still works.

      • Josh H says:

        Same problem. When I drag and drop, I get the thumbnail icon for the image, not the image itself. I have tried re-saving the image, but that didn’t work. Any other ideas?

        • Abbey says:

          Same thing happens to me, I get an icon with the file name and not the image.

          • Krissy says:

            I am having the same issue. Let’s say I save out my logo 300x188pixels at 96 dpi. Whenever I drag it into my mail signature it 1. resizes to be larger than 300 x 188 and is blurry and 2. when viewing on an iphone, it appears as the image file name rather than the logo.

            HELP?!

    Fonts are not copied correctly.

  10. Robert says:

    Directions are dysfunctional, and comments complaining that the directions don’t work are disregarded by whoever created them.

  11. David says:

    1) create a signature as above – with a placeholder image
    2) Quit Mail
    3) In Finder go to user~/Library/Mail/V4/Mail Data/Signatures/
    4) Pick the most recently created crazily named signature file and open it in TextEdit or Text Wrangler
    5) Replace the image file with a publicly available URL for the image you’d like in your signature. If needed, place this on a web-server. The file on the server should be double resolution to not be muddy on retina displays. So 150×30 in your signature should be a 300×60 size file.
    6) Save the modified signature file.
    7) Use Get Info in finder to `lock` this file, otherwise Mail will reverse your changes.
    8) Open Mail and use that signature as usual.
    9) Bonus, send Apple Feedback in Mail to support URL images in Mail natively do end this signature hacking stupidity.
