A single commercial email produces 0.174 g of CO2, compared to 19.5 for the average direct mail letter, according to an analysis from digital marketing platform Sendinblue, conducted by Aktio in 2021.
Moreover, a 2,000-piece email campaign produces 350g of CO2-- half that of a 30-second TV ad, the company says.

Moreover, the average company produces the equivalent of 2,552 tons of CO2, between purchasing electricity for company facilities and unowned indirect emissions like business travel and purchases, based on a 2020 analysis.
Sendinblue has developed an emissions simulator for its platform, which allows clients to calculate an email campaign’s carbon output. This reveals CO2 emissions based on monthly emails sent and is adjusted based on location.
