E.ON and Octopus send virtually the same email received ten minutes apart

Sterlingtimes

Both titled "FYI: Your Direct Debit payment is due soon"

Emails have 95% of the same wording

Octopus signs off: Love and power,
The Octopus Energy team

E.ON signs off: Here's to a brighter future, together.
E.ON Next

Do these respective emails come from the same server?

E.ON Next runs on the same "Kraken" software platform that Octopus developed.

I think BG Evolve also uses Kraken, and EDF are said to have bought a licence but haven't yet gone live with it.

Thank you. That may explain it. I would imagine that there is a unified server here given the proximity of the emails.
