While Glö has transformed wedding invitations with sophisticated design templates and robust technology for email distribution, the success of Glö’s business model depends on their paperless invitations reaching the inbox of their users’ guests.

Glö sends over 18,000 emails each month, but about 30% of their email was routinely being undelivered by the ISPs resulting in numerous customer service calls and complaints from users. While they tried to solve the delivery failures internally, they neither had the time nor the internal expertise to properly diagnose and fix their email deliverability issues. They needed a way to ensure that every paperless invite their customers sent to their guest lists got delivered to the inbox, not the spam folder.


Glö scoured the web for email deliverability solutions. Glö needed a solution with:

  • The architecture to seamlessly handle email deployment and scale for future growth.
  • Expertise to serve as extension of the Glö team should delivery failures arise.
  • Deliverability built into the platform so that Glö could focus on building their product.

Their search turned up two top vendors – one of which was SendGrid. The other had a great reputation in deliverability but their solution was too complex, and geared towards huge organizations who could afford to staff their organizations with deliverability experts to augment their solution. SendGrid became their vendor of choice.


SendGrid’s platform was easy to implement. With access to SendGrid’s robust analytics and tracking tools, Glö gained insights into email delivery and recipient action that they never had before, and were able to achieve:

  • 99% of Email Delivered to the Inbox.Prior to using SendGrid, 30% of Glö’s email routinely went undelivered and user’s had no way of knowing if particular emails had bounced or gone unread. With SendGrid, they can be proactive in preventing delivery issues before they happen, and take advantage of advanced deliverability tools like whitelisting to improve their email delivery rates, and share delivery status directly with their users. Depending on the mail stream, Glö now enjoys email delivery rates ranging between 90-99%. 
  • Less Customer Service Demands. Previously, when paperless invitations didn’t reach the inbox, Glö’s customer service department would be inundated with questions and complaints. Now customer complaints have been virtually eliminated and moreover, they can now share delivery stats of customers’ guest lists. This new level of transparency promotes a level of trust between Glö and its customers, and significantly reduces the number of customer service calls related to email delivery.

As Glö continues to build and expand its customer base, they needed a solution that could grow with them. SendGrid’s platform is fully scalable supporting companies that send billions of emails per month giving Glö’s technology team peace of mind that they made the right decision for long term growth.

Prior to using SendGrid’s platform, 30% of our emails went undelivered. Now, SendGrid’s platform and team of experts have helped us achieve a 99% delivery rate for our paperless invitations. Given these results, this is truly a match made in heaven between Glö and SendGrid.
