Delivery Lore
The frequency conundrum
What is the perfect frequency to send mail? Is it daily, weekly, monthly, hourly, minutely (is that even a word?) or randomly? Any number of experts will give you a definitive answer to this question, but I don’t believe there is a single answer.
The frequency recipients will respond to depends on the type of mail, the recipient expectations, the sender and a host of other factors.
For one example look at the mail sent by social networks. Many people, myself included, will accept dozens of emails a day telling me someone wrote on my Facebook wall or retweeted something I said or wants to link to my network on LinkedIn. Another example is when I’m traveling or waiting to pick up someone who is, I am thrilled to receive multiple updates an hour from the airline.
This willingness to receive frequent commercial or bulk emails doesn’t necessarily translate to marketing emails. When Sur la Table started sending double digit amounts of email a week, I down-subscribed, and had they not let me pick an acceptable-to-me frequency I would have unsubscribed completely.
A lot of marketing experts insist that mailers don’t send frequently enough. That increasing frequency increases ROI. What a lot of people miss are all the caveats in the fine print. In their minds, increasing frequency goes hand in hand with increased segmentation, targeting and recipient specific emails.
The idea isn’t simply to mail the entire list more frequently but to mail those who are more open to increased frequency. This is an idea I wholeheartedly support.

Almost every delivery consultant, delivery expert or deliverability blog offers their secrets to understanding spam filters. As a reader, though, how do you know if the author knows what they’re talking about? For instance, on one of the major delivery blogs had an article today saying that emails with a specific subject line will not get past spam filters.
This type of statement is nothing new. The lore around spam filters and what they do and do not do permeates our industry. Most of the has achieved the status of urban legend, and yet is still repeated as gospel. Proof? I sent an email with the subject line quoted in the above blog post to my aol, yahoo, gmail and hotmail accounts. Within 3 minutes of sending the email it was in the inbox of all 4 accounts
I can come up with any number of reasons why the email ended up in my inbox, rather than being caught by spam filters as the delivery expert originally claimed. But none of those reasons really matter. The expert in question is spreading delivery lore that is demonstrably false. Emails with that subject line will get through spam filters. I even added an extra 4 exclamation points in the subject line.
Not all delivery lore is true. In fact, most lore involving “always” “all” “never” or “none” is not going to be true. Just because you read it on the internet, and because it came from someone claiming to know what they’re talking about does not absolve individual senders from critically thinking about the information.
