The gambling suspension system was introduced to the Swedish market when it was re-regulated on 1 January 2019.
However, the SGA is concerned not enough players know about the service, which has led to a campaign from 15 June that will promote Spelpaus.set on multiple digital channels.
This includes television adverts, as well as promotion on several websites and social media, for at least four weeks. The campaign will start with seven different messages, three of which will be aired as television adverts.
The authority also pointed out the current COVID-19 pandemic has made it even more important for Spelpaus.se to become more mainstream.
SGA communications manager Anders Sims said: "After just under a year, half of all players knew about Spelpaus.se. It’s good, but not good enough.
"With this investment, we mainly want to inform that Spelpaus.se exists, but also pay attention to people of different behaviours that can be a sign of gambling problems, for example that you are playing in secret."
Last week, the Swedish Government approved plans to introduce temporary online gambling restrictions in response to the pandemic.
The measures, which will last from 2 July until the end of the year, include a SEK 5,000 ($534) weekly deposit limit on online casino games and slots, and a set time limit, although horseracing and sports betting are exempt.
