@naveennair is correct, IRCC would have sent two identical e-mails to
@MeghaThimmappa's husband with only the application number and UCI that are different. Perhaps, the husband thought IRCC sent the same e-mail twice and deleted the other one.
What matters is if you used the same e-mail for the two applications. If that's the case, ask your husband to check his junk and deleted mail folders.
Meanwhile, do you mind providing your application's details so we can add it to the sheet?
