Email is worthless

I’m ready to go back to mailing letters, maybe those will get read.

I owe money.

deliver check, get receipt.

send email, did this get credited?

please reply with check no. and date delivered.

fine, here it is

next day, did this get handled? Nothing, no response 

2 days later same exact person sends me collection letter via email big giant WTF???

I already paid this YOU CASHED THE DAMN CHECK.

Maybe try the phone tomorrow, remember those?

there’s so much spam (including from the employer safety fiscal training this message that message-I call it Department spam) that 90% of the real messages get buried.
