The ability to customize our emails has been one thing I love about spend go so far! It's also super easy to send out email newsletters if you just need something quick without having too many customization options available at once (which would be overwhelming). In my organization we're able use it both internally & externally. There are times when there may not have any open transactions within your account but still get notifications from other accounts/brands which makes tracking difficult sometimes since they don't always display what transaction was opened up. If anyone needs help reaching new clients who haven’t made contact yet this really helps us do exactly that!! So much easier than cold calling or using social media advertising like some providers offer now days. The ability to create customized email templates and send them out in bulk is very useful. It's easy to use and has many features. I wish there was a way to have it auto-assign emails to people once you hit send. I also wish it could be used outside of Gmail. It would be great if they added other email providers such as Outlook.com. We are able to send out mass emails to our clients about upcoming events and services we offer.
