Constant Contact is for the small business owner who wants to quickly get started with organized email marketing and doesn’t anticipate needing any advanced functionality down the line. The tool is a great choice for you if you fit this description, but if you plan to expand your marketing automation efforts in the near future, this isn’t the tool for you.
Infusionsoft is a fully functional CRM and marketing solution created for small and medium-size businesses. Comparing it to Mailchimp or AWeber is like comparing a Lamborghini to a VW Golf. It provides highly advanced features for list segmentation, lead scoring, and marketing automation. On top of all that, you can integrate all of these features with your optin form using Infusionsoft Tags + OptinMonster.
