Lets you send mass cold emails and follow up emails. You can choose when and on what condition a follow-up email should be sent (e.g. send if there is no response in five days). It is very customizable. You can import bulk email addresses with CSV files and unlike other similar products in Wavo duplicate addresses are automatically detected. It also has a simple but precise reporting system. Review collected by and hosted on G2.com.
