I love that it's easy to set up campaigns, track results and send data analytics reports to customers easily for free (also there is a paid plan). You can also get insights from customer behavior so you know what works best! It requires some training but after watching their webinars or taking an online class they do make things pretty clear about how to use it effectively in no time at all. The integration with Mailchimp would be great if it was more seamless. We've been using it to help drive traffic to our website. I like that it's easy to integrate into our website, making it super simple for users to send emails from their own domain. It also helps us manage all of those campaigns in one place! The reporting can be difficult at times - but we're working through them as they are still very new features. We love how well integrated this is with MailChimp so no extra work required when using both services together. Sending out newsletters/emails has been simplified since switching over to Sendlane.
