I need to retrieve an email I accidentally deleted from my spam box

Hi Zoho Team,

I did send an email to support(at)zohomail(dot)com last night and I also phoned Zoho to see if they could help. Yesterday evening (16th June between 8:05-8:25pm) I accidentally deleted a very important email from my spam box. I then realised by googling that once I deleted it from the spam it hasn't gone in to the trash or deleted messages. I was hoping there is some way to retrieve this mail as it was very very important and I didn't mean to delete it.

Would really appreciate any help
Thank you - Laura
