Oxyleads also has a neat feature called Email Campaigns. With it, you can schedule email delivery, create personalized email templates, email campaigns, and get comprehensive statistics on key performance metrics.
To start using Email Campaigns you will be asked to sign in with your Google account. Once you do this, you will be able to create your first Campaign by going to My Campaigns and clicking on the New campaign button at the top of your dashboard. Take note that Email Campaigns are in beta, so we are still working on making it better - so any comments are very much welcome.
