“Gravitec.net is the first push platform with the Spanish interface. We provide Latin America marketers with the service in their native language so that they can use push notifications in a most convenient way.” — Denis Zernyshkin, CEO at Gravitec.net
The hero of this case study is the Prensa Libre company that owns two websites.
- Prensalibre.com is a flagship digital newspaper in Guatemala
- Guatevision.com is an online TV
Both websites use push notifications by Gravitec.net to inform their readers about their last updates. The average traffic of these two websites is roughly 5,8 million visits per month.
Here we review the Prensa Libre experience of leveraging push notifications.
Subscriber base growth
The Prensa Libre team has included push notifications into their marketing strategy since January 2019. Since that time, their subscriber base is rapidly growing.
TIP
On the graph below, you can see the base growth rates of the Prensa Libre website during the four-months period from January to April 2019.
In February and March, the number of new subscribers was up to 230 000. Gradually, the growth rate was decreasing. This is typical for any website because regular visitors subscribs in the first two-three months. Nevertheless, the total number of subscribers always increases.
The table below shows some patterns of how the website was getting new subscriptions week by week. 
The next chart shows the statistics on subscriptions for Guate Vision during the same period — January-April 2019.
The online TV has less website traffic compared to Prensa Libre, and this results into less subscriptions per month, but still the base growth was significant. The number of new subscribers in April was up to 90 000.
Opt-out and growth rate in percentage
TIP
The opt-out rate for Prensa Libre was 20%.
The chart below shows how this affected the growth rate of subscriptions. In March 2019, the base growth was as high as 300% even with the opt-out rate of 20%. In April, the growth rate was 60%, and in May — 30%.
The opt-out rate for Guate Vision was 30%, but still the growth rate was up to 370% in April, and up to 90% in May.
- Guate Vision
As we mentioned above, the growth decline over time is a common process. The highest results are typical for the first few months after the installation of push notifications. Still, subscriber base for both websites is steadily increasing.
Delivery rate
The delivery rate for both websites is nearly the same. It’s about 55 -65%.
It results in 1 million received messages for the campaign of 1.8 million sent notifications.
Push campaigns and CTR
The Prensa Libre company sends push campaigns 3-5 times per day.
On the graph below, we can see the number of sent notifications in February-March’19 by Prensa Libre website.
And there is statistics of Guate Vision push campaigns in March-April 2019.
And here on the bubble chart, we can see the number of clicks for all campaigns by Prensa Libre.
The marked bubble by 3/30/2019 shows the next results.
- The number of sent notifications — 191 900
- CTR — 11.92%
- Clicks number – 22 768
- The notification title – ‘Urgente’
Another example shows the results of a push campaign with the huge number of sent notifications.
On March 20, the company sent five push campaigns per day. The total amount of sent notifications was up to 1.8 million. The number of clicked messages was over 68 000.
We can compare all campaigns results for both websites on two bubble charts.
The highest CTR of Prensa Libre push notifications was over 20% and in average, it’s about 8%. 
An average CTR according to Guate Vision statistics is also roughly 8%.
