Email tracking pixel SPAM issue!
Through doing some email spam testing, I found something concerning - which was confirmed by support - that the tracking pixel is not being given an alt tag.
Missing Alt tags are red flags for spam filters and on testing with mail-tester.com I cannot score over 9.5/10 with a HubSpot email.
Ever the perfectionist, and with the trickiness of getting into some inboxes, particularly Microsoft accounts, this is upsetting and definitely an easy fix to resolve!
I'm not sure I agree with HubSpot's stance that "the contact does not interact with the image itself, and therefore we don't believe crawlers need to know more about the image by way of the alt" - I don't think spam filters are quite so sophisticated on that level, and simply see a image without an alt tag.
While a score of 9.5/10 is by no means going to land you in spam if you have good deliverability and follow all the best practices, that 0.5 could tip some of the more spam-riskily-worded emails over the line, or at least into the Promotions/Other folders in Gmail/Outlook.
This should be a super straightforward fix, and would allow us email perfectionists sleep a little better at night ha!
