I’m trying to integrate a Gmail quick action button into emails sent from my iOS application using MFMailComposeViewController. I created an HTML template that includes a JSON-LD script, but when I send a test email, the quick action button doesn’t appear in Gmail.
Below is a revised version of my code:
let mailController = MFMailComposeViewController()
mailController.setSubject("Test Email")
let htmlContent = "<html><head><script type='application/ld+json'>{\"@context\": \"http://schema.org\", \"@type\": \"EmailMessage\", \"description\": \"Check this out\", \"action\": {\"@type\": \"ViewAction\", \"url\": \"https://example.com/action\"}}</script></head><body>Email content goes here</body></html>"
mailController.setMessageBody(htmlContent, isHTML: true)
I reviewed the email source and confirmed that the JSON-LD script is present, yet the quick action button is still missing in Gmail. Am I overlooking a configuration step? Does this method correctly support Gmail quick actions when using MFMailComposeViewController, or is there an alternative approach I should try?
I’ve dealt with this exact problem in one of my projects. MFMailComposeViewController is great for basic emails, but it’s not ideal for advanced features like Gmail’s quick actions.
Here’s what worked for me:
I switched to using the Mailgun API. It gives you way more control over the email structure, including headers and custom metadata. With Mailgun, I could properly insert the JSON-LD script in the right place.
Another tip: make sure your JSON-LD is escaped correctly. Gmail’s parser is pretty finicky. I had to play around with different escape methods before it worked consistently.
Also, don’t forget to test on multiple devices and email clients. What works in Gmail might not work in Outlook or Apple Mail. It’s a pain, but necessary for a smooth user experience.
Lastly, be patient with testing. Sometimes it took up to 24 hours for the quick actions to show up in my inbox. Keep at it, and you’ll get there!
hey mate, i’ve had similar issues. MFMailComposeViewController might not fully support Gmail’s quick actions. have u tried using MessageUI framework instead? it gives more control over email content. also, double-check ur JSON-LD syntax - Gmail can be picky. good luck!
I’ve encountered this problem before. Gmail’s quick actions require specific formatting and headers that MFMailComposeViewController doesn’t natively support. Instead, consider using a third-party email library like MailCore2 or SwiftSMTP. These offer more flexibility in constructing email headers and content.
Also, ensure your JSON-LD is properly encoded and placed in the section. Gmail’s parsing can be strict. You might need to experiment with different placements and encodings.
Lastly, remember that quick actions may not appear immediately after sending. Gmail sometimes takes time to process and display them. Test your implementation by sending emails to yourself and checking after a few hours.
