They definitely have good credibility and I see no issues with getting paid your commissions for your sales.

Never tried it personally, but they've been around for quite some time so I'm sure they're paying their affiliates.

Builderall has crafted a pretty compelling affiliate offer. We love the multi-tier commission structure and the sheer wealth of products you can promote. In our view, the only real downside is the competitiveness of the niche, which means you'll have to work hard to build reliable free traffic sources.

I switched everything over from Mailchimp to Active Campaign about 2 years ago. And never looked back. My profit doubled in the first year.

I am a Digital Marketer, and I use AWeber for my affiliate marketing. The product addresses several business problems for me, including the need to build and maintain a list of subscribers, create and send targeted email campaigns, and track the performance of those campaigns. With AWeber, I can create opt-in forms and landing pages to capture email addresses from website visitors. 

AWeber also provides reporting and analytics tools to help affiliate marketers track the performance of their email campaigns and make data-driven decisions about future campaigns. The scope of use cases for AWeber in affiliate marketing is quite broad, ranging from individual affiliates promoting products to large affiliate networks managing multiple campaigns across various niches. Some common use cases include Building an email list, Promoting products, Nurturing leads, Reporting and analytics. Overall, AWeber provides a robust set of tools for me to build and maintain their email lists, create targeted campaigns, and track their performance.
Pros and Cons:
1. AWeber's automation features are robust and flexible. I can set up automation workflows based on a variety of triggers, such as when someone subscribes to a list or clicks a link.
2. AWeber's landing page builder makes it easy to create professional-looking landing pages without any coding experience. I can choose from a variety of templates, customize them with my own branding, and publish them.
3. AWeber provides detailed reporting and analytics on every aspect of an affiliate's email campaigns, including open rates, click-through rates, conversion rates, revenue generated, and more.
4. AWeber's landing page builder lacks advanced customization options, making it challenging to create unique and eye-catching landing pages.
5. AWeber's email template library is limited compared to its competitors. While the platform offers a wide range of templates.
6. Email is not properly optimized, I mean sometimes email mobile interface is not optimized.

Setting it up and beginning to make templates for emails was fairly easy. What I like the most is the customer support. And I love the fact that they embrace affiliate marketers without any worry of penalty.

CONS:
There are a few features that have to do with adding in graphics to emails that are a big clunky to work with. But even though I wouldn't choose to do things this way, there's always a workaround.

REASON FOR CHOOSING SENDLANE:
Price, ease of use.
REASONS FOR SWITCHING TO SENDLANE:
Active Campaign shut me down in the middle of a huge promo. I lost thousands of dollars. There was NO good reason, and they apologized and told me we "could work it out." NO THANKS!!

Was good till lately when I am now on probation. I paid the full year

PROS
1. Easy to use and understand. I’m new so I found it easy to use and understand.

CONS
1. Didn’t know that’s clicks mattered that much.
