Summary
What email marketers say12Marketer opinions
Email marketer from Email on Acid shares that many email clients block images by default, impacting the effectiveness of image-heavy emails. Using alt text and optimizing the text-to-image ratio can mitigate this issue, ensuring that the message is still conveyed even when images are blocked. This maintains user interest and helps improve open rates.

Marketer from Email Geeks explains that images alone are unlikely to cause deliverability issues, as filters are mainly behavioral. Low open rates can be caused by various factors unrelated to filtering, such as user apathy or full inboxes. He advises to look at bounces, complaints, and unsubscribes to see if they are up. Also use Google Postmaster Tools and to check open rates across different providers to identify potential filtering issues.
