While most experts will say there's no such thing as the perfect time  for 
email marketing to send your email offer or newsletter, conventional wisdom holds that  Tuesday—generally speaking—is the best day for a campaign, and Friday  the worst.
"The theory behind the rule of thumb makes sense," notes Caroline  Ruggiero at the Marketo blog. "[E]mail too early in the week and people  are too busy with their actual work to open or focus on your message.  Email end of the week and your message will get buried in a barrage of  messages everyone has to dig out of come Monday morning."
But her own preference for browsing work email on Sundays made her  wonder if Sunday could be the new Tuesday for email marketers. Although  the weekend is a time to unwind, she explains, "it's also a time to  catch up on newsletters, lower-priority messages, and feeds without the  distraction of, well, work. I am absolutely more open to reading  marketing messages in this quieter, more relaxed setting."
There's some evidence that she's not alone in her habit:
	- An AOL survey found that 62% of respondents checked their work email over the weekend.
 
	- According to a Pew study, two thirds of Americans do work-related research at home.
 
The only way to know whether your B2B audience reads email on  weekends is—of course—to test it. "Perhaps," says Ruggiero, "your key  target might be guilty of indulging in some Sunday work email, just like  me."
So here it goes: Sunday might work. Don't just  assume that weekdays are the best time to reach your customers. If you  check your email over the weekend, it stands to reason that they might,  too.
