One of the best feature of Aweber eMail form creator is, you can have extra field apart from Name and eMail. For example, if you need to get the Address or Phone number from your subscribe, you can do that by adding a new field. (The step is easy to do and even with zero design and coding skills you can do that). What I suggest is, simply select any template from the page and you are good to add Aweber sign-up form on your blog.
If you’d like to check out ConvertKit, my referral link is here [Full Disclosure: I’m a compensated advisor and an affiliate for ConvertKit], and if you have any questions about ConvertKit, both Nathan and I will be actively popping in and out of this post to reply, however we’re currently at the LeadPages conference in Minneapolis so we may be slow to reply at first.
Using the Personalize dropdown, you can insert custom snippets like your subscribers first name, or sign up date, and AWeber will automatically insert that data specific to each subscriber if we have it. If you collect first name, for example, you can send an email that says Hello Tom, or Hello Mary, or Hello John, depending upon who you’re sending to.
