Gmail treats HTML email as quoted content when sent via Swift

I’m having trouble with an HTML email I’m sending through Swift. The email is pretty basic - just a holiday greeting image that’s centered on the page. Everything works great in most email clients like Thunderbird, Outlook Express, and Yahoo Mail. But when someone opens it in Gmail, the whole email gets hidden behind a “Show quoted content” link. Users have to click that tiny link to actually see the email content. This is really frustrating because most people probably won’t even notice that link. Has anyone else run into this issue? What causes Gmail to think the email content is quoted text instead of the actual message?

Gmail’s quote detection gets really sensitive with HTML emails. Since your email is mostly a holiday greeting image, Gmail’s probably seeing your HTML patterns as quoted content - this happens a lot when there’s more HTML than actual text. Try adding a short plain text message above the image for context. Also, clean up your HTML structure and ditch any unnecessary nested elements. Check your reply-to headers too - sometimes threading data confuses Gmail’s detection.

Gmail’s quote detection algorithm kicks in when it spots certain HTML patterns or email headers. Your Swift code is probably creating problematic headers or HTML structure. First, check if you’re accidentally adding threading headers like In-Reply-To or References - Gmail uses these to figure out email relationships and might flag your content as quoted text. Also, if you’re using blockquote tags or indented divs to center your image, that’s likely the problem. Gmail sees those as quoted content. Instead, use CSS margin auto for centering and ditch the nested divs. Make sure your message headers are clean without any reply metadata.

i’ve had that issue too! gmail can be picky with the styling in html emails. try to keep it simple and avoid using too much css that can confuse it. also, removing any old headers like “from:” in ur html can hlp avoid these probs.
