As a software developer protecting your hard work is an important aspect of selling digital products. You want a licensing system that does what you need, is flexible and not get in your way. ProductDyno does that and more. Other licensing systems make you jump through hoops integrating their services, not so with ProductDyno, it… “Protecting Your Hard Work Is Important”
In ConvertKit, this is much easier. Unlike Aweber where you set up separate lists (I had 63 lists when I shut my account down), in ConvertKit, you don’t have lists at all. Instead, you use tags and automation rules to segment your audience. So I can have someone go through a nurture sequence (when they first join my list) while still sending my blog/podcast broadcasts to my main list. I simply create a rule:

Yes, one of the more popular features they offer is their in-depth analytics. This allows you to see things like open rate and click-through rates. It also makes it easy to take action on your stats. For example, you can easily resend a newsletter to anyone who didn’t open the first email or create a segment based on people who clicked a specific link.
As its name implies, Drip is an email automation tool that is specifically designed for drip emails. If you’re pressed for time to create your own email content, you can use Drip’s Blueprints, or premade sets of drip campaigns with filler text that you can easily tweak to your own liking. Additionally, this tool allows you to collect email addresses for your drip campaigns via a simple widget that you can add to your website
Another thing about your list. Don’t worry when people unsubscribe — because they will. There are a variety of reasons so don’t take it personal. Maybe they’re just reducing the size of their inbox. Or perhaps they were just interested in your freebie offer. Chance are they were not going to buy from you anyway. Just keep providing quality content and those who join will far exceed those who choose to unsubscribe.
Now don't tell Aweber, but I signed up to every one of the lists I created in my account. I signed up with disposable email accounts. I signed up with Yahoo mail.  I signed up with Gmail. I signed up with abut half a dozen different accounts. Guess what?  Every email hit the inbox. Every. single. one.  When you are building your list, you HAVE to KNOW that the emails are going to stand every chance of being seen and opened by your subscribers.  Why else would you send emails right?
To manage expectations, it’s a good idea to send your subscribers a quick follow-up email immediately after they’ve subscribed. This is an optimal opportunity for you to, not only thank them for subscribing, but to also to introduce yourself, send them material that you think they’ll be interested in as new subscribers and remind them how often to expect your messages. Almost all email service providers give you the option to create an autoresponder workflows (something we’ll talk about a little bit later), so use it!
Variations of “Hello {!firstname_fix}” have become the norm in email marketing, not the outlier. Because of that, it’s losing its effectiveness. You can still use name personalization, but you also want to think about going a step further. At AWeber, we recommend segmenting your audience and sending each segment tailored messages with unique subject lines.
I actually use both services today so I can keep this review up to date. Overall, I think Aweber has a better deliverability rate which is a huge reason to use them. Furthermore, i like the way they do autoresponders much better than MC. On the flip side, MC has a much easier to use API if you are into coding and manipulating your lists programmatically.

A cool way to tease your email content is to syndicate your content on a platform like Medium or LinkedIn Pulse. Or, team up with an influencer in your space to help spread the word about the awesome content you’re sending through email. The more you promote yourself to relevant communities and groups, the more likely you are to keep your email list growing and growing.

Tip: We often suggest that you mention what you’re going to talk about in your subject line. However, Nathan Latka of Heyo once told us in a webinar that he usually goes for a really short subject line that provokes curiosity. (He claims he has even used knock-knock jokes.) In the right context, something like “Hey …” can be surprisingly effective. The casual and familiar tone coupled with the slight recognition of your email address may be enough to prompt an open.
On the flip side, Aweber’s method of managing followup emails allows me to know exactly which subscriber has received which follow up emails and when. With MailChimp, I really have no clue who has or hasn’t received a particular email. Overall, I kind of prefer Aweber’s method of managing follow-ups but it is basically a wash depending on your preference.

Litmus recommends around 50 characters. Yes Lifecycle Marketing says emails with subject line up to 20 characters have ethe highest average open rate, unique click rate, and click-to-open rate. An analysis from Retention Science found that subject lines with 6 to 10 words results in the highest open rates. And Return Path advises using 61 to 70 characters.

I have used Aweber for years, but wondered is I should try another service. One thing I do not like about Aweber is they don’t allow you to upload a list of contacts. I know that some of the other companies do. So, I appreciate your comparison. It makes Aweber a little more comfortable. If anyone is interested I do have a free booklet on “71 Ways to Get Free Traffic” that can be found here Thanks for the article.

Wow, Gill! That’s a fantastic idea. No wonder you got such great engagement. At AWeber, we’ve found that specificity does lead to higher open rates. It shows you know your audience, and you’re sending them value. You’re talking to the individual — not the crowd. Highly relevant subject lines paired with segmentation is a winning duo. Keep up the awesome work.

Alex GetResponse is a good service too. They have a smaller customer base than MailChimp or Aweber but they are definitely on the right track. You should consider your own options that will help you decide. For example, pricing, growth, support, reliability, deliverability, spam filters, etc. Make a list of these factors to compare on your own, you will also find such analysis around the web but those analysis could be biased towards one of the service. So you better do it on your own.

Opt-in rates have been on the decline for the last decade or so, and I’ve tried a lot of different solutions that have promised to turn that trend around. Of all the things I’ve tried including web based apps and various plugins, only Post Gopher actually delivered. I installed it on my blog and… “Post Gopher Has Performed Better Than All The Other List Building Solutions I Use Combined!”
The first fifteen minutes of our in-person conversation was purely catching up and discussing upcoming family vacations, but then we dove right into the conversation about email marketing. It was not a pitch to join his platform at all. In fact, there was none of that except for a small but expected, “Hey, if Infusionsoft doesn’t work out for you, let me know, and we can see how you might be able to use ConvertKit.”
You may sustain a total loss of the funds that you deposit with your broker to establish or maintain a position in the commodity futures market or foreign exchange market, and you may incur losses beyond these amounts. If the market moves against your position, you may be called upon by your broker to deposit a substantial amount of additional margin funds, on short notice, in order to maintain your position. If you do not provide the required funds within the time required by your broker, your position may be liquidated at a loss, and you will be liable for any resulting deficit in your account.
Enter the autoresponder. The autoreposnder (or as ConvertKit calls it, a Course), is a series of messages that get sent in succession automatically. You write them once, determine the frequency, and then subscribers get these same messages no matter when they join your list. It’s a fabulous strategy because you build it once and then you can rest knowing that even if you can’t send something in real-time, they are still getting these carefully crafted emails.
Since finding your great IM teachings and fantastic products I can honestly say my business has been taken to the next level. My lists are growing faster than I ever imagined possible! I now feel - no - I now know - I have a real online business – thanks to you I have access to fantastic products. Every week you seem to release a new product – which is great for me I will never be short of products to promote. I would like to thank you for this Golden opportunity - I totally believe if I can’t make money online now there is something seriously wrong with me! - David Knight
You see, the people on your email list are your best customers.  They have visited your site and found it interesting enough to subscribe for more content.  For that reason alone, they are much more likely to listen to any offers you may send them (affiliate promotions, product sales, discount coupons, etc.).  So, having a large email list can actually be quite profitable, which is why bloggers and website owners hold them in such high regard.
