Amply

Crunchbase | Website | Twitter | Facebook | Linkedin

Amply is a cloud-based email delivery service that allows you to send email without the cost and headache that comes with managing your own email servers. Amply’s analytics engine helps companies gain actionable insight around the email they send.

Before Amply, companies had to rely on ambiguous statistics to evaluate user engagement with their email. This absence in engagement data led to companies approaching their email programs through trial and error, which is costly and inefficient.

Since transactional and marketing email are pivotal to how companies engage with their customers, they cannot afford to shoot in the dark. Now, those companies can leverage Amply’s analytics platform to get to know their users at a much higher level.

The data we extract gives you an in-depth understanding of your email health and performance, and helps you answer critical questions about your users.. .

Groups.io

Crunchbase | Website | Twitter | Facebook | Linkedin

Groups.io is an email groups service that enables users to find and start groups, sync members across services, and archive conversations with hashtags. The system works with Dropbox, Email, Github, Feeds, Google Hangouts, Facebook, and Instagram.

Users can create an announcement, moderated, or restricted group; customize the various welcome, goodbye, monthly, and pending subscription messages; define multiple owners and moderators; monitor the group through the activity log and and track email delivery to members; approve messages from moderated users through either the website or via email; set up events in the group calendar and upload files to the Files section; and create a wiki to store group knowledge. Those who have a Slack Team can sync it with their Groups.iogroup so that when someone joins their group, they will be automatically invited to join the Slack Team and if someone leaves their group, they will be removed from the Slack Team.

They can tag message threads by including hashtags in the subject, restrict them to a predefined set, and search archives by tag. They can mute individual threads and hashtags; and receive every message, opt to receive only the first message in a thread with the option to follow the thread later, opt to receive only messages in threads that they start, or opt to receive no emails at all.

Groups.io was launched by Mark Fletcher and is operated from Portola Valley, California, United States.. .
