Zapier is used to create integrations between Salesmate and Drip eliminating the need to double enter all the client data into our email lists. In addition we also have it setup to export certain lead info into a Google sheet for tracking & remarket lists. Though Leadpages & Drip have a native integration process you can also opt to setup with Zapier for multiple triggers.
Microsoft Flow and Automate IO were both alternatives we looked into but fell short of our requirements. From a pricing and ease of use standpoint Automate IO definitely fit the bill but didn't integrate with Salesmate so that was a bust. As for Microsoft Flow it's also an excellent alternative and a very stable platform however it only offers a select amount of integrations ultimately pushing me to go with Zapier.
Zapier is a must have for small businesses looking to grow without the substantial cost of hiring additional admin staff. Although the initial setup is tedious in the long run it will not only speed up the sales process and save a significant amount of time, you'll wonder how you operated without it in the back end.
When it comes to automating processes the single most important factor is application integration availability, little to no down time, and an IT dept that's always working to better the processes, integration availability, and process options.
