Increased email size: Adding images to your email signature can significantly increase the size of your emails. This can make them take longer to send and receive, particularly for users with slow internet connections.
Distraction: Images in email signatures can be distracting for the recipient, particularly if they are large or animated. This can take away from the content of the email itself and decrease its impact.
Inconsistent display: Email clients and webmail services may display images in email signatures differently, or not display them at all. This can lead to inconsistent branding or information being missed by the recipient.
Spam filters: Including images in email signatures can trigger spam filters, especially if the image is hosted on an external server. This can cause your email to be flagged as spam or sent to the recipient's junk folder.
Accessibility: Some email clients or users may have accessibility needs that require them to use text-based email clients, which may not support images in email signatures.
Professionalism: Images in email signatures can give the impression of unprofessionalism, particularly if the image is of poor quality or not relevant to the content of the email.
Mobile devices: Many email clients are accessed on mobile devices, which may have limited screen space. Images in email signatures can take up valuable space and make the email difficult to read on a mobile device.
