I ordered a mailing to 1M people in US/Canada for my website (it's a 'product discovery' site). I can choose between sending it the 29th -Black Friday- or a week later. Any e-mail marketing expert here who can shine his light on this? On the hand people go crazy on Black Friday and are focused on buying, on the other hand every online store is e-mailing like crazy that day and it will be hard to stand out.
