After you get their communication, you can compare them and understand which ones are worth advertising with and which you can forget, at least for now. To decide whether an ezine is a good pick, check to be certain its web page is not on a free platform like Blogger or Wordpress. Make sure that they obviously state what they offer vis advertising.
As far as the emails you’ll be getting from each ezine, first make sure that you may opt-in two times to receive the newsletter. This makes sure the subscriber base is reactive. Also, check to see that the publisher informs you of the sorts of emails that they can accept. Many email suppliers block spam.
If the ezine will not allow you to use a few of these, this is a great thing. It implies that mails will be delivered to recipients rather than to the junk box. If you are receiving one or more email per day from the ezine, you don’t want to advertise with them. That is too much competition. And you only need to go with the ones that have “real” subject lines offered by the advertiser and not by the publisher. You need to be able to build your own subject line for your ads. Check out the content of the newsletters you are receiving. If it is high-value content and not just ads, then it’s worth going for.
You could have more than one ezine advertising service which has passed your “test”. At about that point, just go with the least pricey one.
