Back then Infusionsoft was breakthrough. There wasn't any real competition if you wanted all in one. We migrated from ACT and iContact back in 2008. But that has all changed in recent years and Infusionsoft has the ugly reputation it has for a number of reasons. Can't live with it any longer.
Today, take your time working with a real trusted adviser whom you are wiling to pay to help you make a fully informed decision based on you, your team and your business, sales and marketing goals. There are many great alternatives on the market today. Thank goodness. Solutions like this make it way easier to start, fund, market, sell, manage and scale any small business. There are tons of success stories when it comes to marketing automation campaigns for both B2B and B2C. There are also tons of train wrecks regardless of the technology solution. You can't go into any of these solutions half-assed. You have to be prepared to really dig in yourself, ask if this is the best and most productive use of your time and determine at what point you need to hire outside or in house talent you can really trust to take the lead.
Make sure you have a great person to run this or other automation systems.
