I’ll introduce the topic of Microsoft Outlook’s URL character limit of 1024 characters.
Background: URLs Get Cut Off in Outlook
I encountered a case where when opening an HTML email with URLs of 2000+ characters linked in the email body in Microsoft Outlook, the URLs were cut off at 1024 characters, making them invalid and unable to open.
Through this incident, I learned that Outlook has a URL character limit of 1024 characters.
Solution: Keep URL Character Count Under 1024
I thought it would be fine since I was using a href for linking, but apparently that wasn’t the case.
Option: Use URL Shortening Services
Use URL shortening services like Bitly.
Option: Implement URL Shortening Service
Implementing your own URL shortening service is another approach.
For example, if you’re sending emails from backend or batch processing, you might need to implement your own URL shortening functionality.
That’s all from the Gemba about being troubled by URLs getting cut off due to Outlook’s 1024 character URL limit.
