Gmail is stacking different subject emails while my client wants only same subject should be stack. I did a lot of testing and found that subject starting from [text] are ignored.
whatever you put inside [ ] will be ignored if you starting a subject with there rackets. But if you put these at the end this will be considered as a new subject.
I tested with different subjects
- Test subject
- Test subject [email new]
- Test subject [new email]
- [new email] Test subject
- [email new] Test subject
and found the below result.
Test subject , [new email] Test subject , [email new] Test subject are stacked together.
