I typically either try to have a list setup to email daily, or every other day, but not every day is a CPA (or money making) promotion.. i try to keep the majority of the emails good content that will benefit the receiver, or at least give them information they want, then every once and a while sneak in an offer or a way to make some money off them

Depends on niche, but mostly what i have seen people more response to is. 2 useful email in a week with no advertising in it just information quality (preselling the product) and then i will send them a 3rd email with cpa in them.

I ran a test. Sending to my list daily or every 3 days. Made much more sending daily.

I do daily, bi-daily, or weekly.

Depends on my goal.

Sending every 2 or 3 days works effectively. What matter most is consistency though. Whether or not you send every week or every day try to send at the same time every time. This way there is an expectancy from your subscriber whether or not they want to read it. Also, if you are going to send a few emails per week have some structure and value to what you send. Email #1 could be information or advice. Email #2 a Free Offer or service. Email #3 Discussion or a link to valuable info on your site. Email #4 a promotion.
Expectancy and the ritual of this will increase open rates and keep a healthy relationship.
As for unsubscribes who needs them - move on and deal with the people who are interested.

I think that if you send every day people can cancel subscription. I think 2-3 times a week is just great.

It depends on what you are sending to them. If these are informative e-mails, I think it's okay to send them daily just as long as they receive something useful from it. For other e-mails, the average is three times a week.

you do not want to come across as a spammer, but then again, be warned if you build a list and then plan to email them once a month, you are failing as a list builder, as they will pretty much forget who you are after a while.

I like piggy in the middle, I make sure I keep them entertained, but do not annoy them, and email 2-3 times a week. Also I like to catch them in the mornings before they go to work, or straight after they get home 6pm - 7pm times work best.

Remember its about trust, so if you can do that, you will get nice open rates and good responses. Make sure they look forward to your email, not see you in their inbox, and GO, "oh not this DH again!, what is he selling this time!" LOL I guess you know what I mean.

Give it a test. If you can provide people value, it can work amazing.

I'm following the Eben Pagan model of sending people long emails (he claims one email was 37 pages long printed, not sure about that). They are entirely content heavy with very little promotion in them as I build my list and things to offer. I'm trying to spread these out every 2-3 days in an autoresponder chain for the first 2-3 weeks as follow-ups to my initial offer.

After that, though, I'm not sure. A few similar sites just send their entire blog post for the day in an email. I feel like that gets people not you visit your site and see the other stuff you've got for them - the stuff that sells. Thoughts?

MailChimp won't let you do make money online or biz-opp.

So I use Aweber.

And always single opt-in. Also I don't think MailChimp allows single opt-in.

Every CPA network's rules are different, you'll have to check with them.

Every 3 days has worked the best for me. However, it depends on many factors.

That depends on your market and subscriber's condition.
I send 2 emails a week. so they dont forget me and also they don't get sick of me.

I am using the rule of 3.. Email every 3rd day and monetize every 3rd email. Works for me

Everybody has their own style. And it's important to point out that a list isn't the only means to make money...a majority of money online is not made through email marketing...in fact, it makes up a tiny portion of commerce online.

With that said, many info marketers do email marketing

And each has their own style. Many mail offers every single day and others once a week. There is no right way as I've seen people who mail once a month make more than some who mail every day and vice versa.

Generally, people are constantly building their list as some subscribers drop off and some become more responsive each and every day.

Me personally, I don't make email marketing a focus. If you're on my list, you'll see that I don't promote much and don't even have a scheduled frequency. Probably 90% of my emails aren't pitching anything.

In my mind, I view the relationships I build from my list as more valuable than any affiliate promo. I still do promote stuff that I think my subscribers will benefit from and I feel it's my obligation to do so, but it's certainly not a huge profit center in my business.

So I guess the point is...there ISN'T a right or wrong way to do email marketing...and you don't even need to do it in the first place!
