Email Marketing

Mine too, instinctively.

But it does depend on who the people are and what they were looking for. If they're people with a really immediate and drastic problem ("house foreclosure" niche?) then they're looking for something immediate and my timetable above is going to be too slow: you'd lose them to someone else.

My belief is that, in general, people who send an email every day for the first 2 weeks, without having made it clear at the opt-in stage that that's what going to happen, are going to get some "unsubscribes"; and they're going to justify it to themselves by pretending that those people "wouldn't have been customers anyway" and/or that they'll do better out of the others who remain that way, so it's worth it. Call me a skepchick but I don't believe a word of it, and strangely(?) they often haven't actually tested it properly but are copying it from people from also haven't actually tested it properly.

I did some testing in 4 of my 8 niches (it's really difficult to test, especially when you're not attracting very large numbers! ), including asking subscribers, and gradually realised that about once every 5 days was probably going to maintain open-rates and interest, and minimise opt-outs, and still enable me to do what I wanted.

But I wouldn't start off at one email every 5 days, because I think that'll make a list unresponsive as it's not enough when they're "new and fresh and interested". So I had to have a way of getting from immediate contact to once in 5 days, and decided intervals of 1, 2, 3, 4 and then 5 days would do it. And it seemed to work better than anything else I tried.

In other words, a bit of testing, a bit of asking subscribers and a bit of guesswork. Nothing terribly useful there, perhaps.

In my case, although all my niches are totally unrelated, I'm attracting the same "end of the market" (i.e. related subscriber demographics) in every niche I touch, because of the way I attract the people to my lists in the first place, and this is obviously significant.

I'm specifically aiming - in all my niches - at attracting predominantly upmarket, educated, literate, affluent, middle-aged, English-speaking people some of whom perhaps have slight reluctance to buy online (i.e. often won't buy from others but might from me) and want to learn about the subject, too ... because I'm an article marketer and that's the style in which I can naturally write anyway. It's an enormous market which perhaps comparatively few other affiliate marketers specifically address, I think. My suspicion is that it's widely and wrongly believed that this is a too-small and too-limited end of the market. I'm basically writing "for my parents and people like them". I do think that "who the people are and how you attract them" is probably highly relevant to the answer to this question.
