Emails from eBay members asking questions come through as email@example.com which can make them hard to count as a group
The following R script re-codes them so they can be counted.
install.packages("plyr") library(plyr) setwd("/home/mike/Desktop") dir() inbox<-read.csv("inbox.TXT", sep="\t") names(inbox) inbox$EADD <- ifelse(grepl("members.ebay.co.uk",inbox$From...Address.), "members.ebay.co.uk" , c(as.character(inbox$From...Address.))) str(inbox) f <- ddply(inbox,c("EADD"),summarize,N=length(EADD)) plot(f$N) head(f[order(-f$N),]) str(f)
Once you've identified the biggest culprits, make a rule to move or delete them from your email.
