🌴 Windletter goes on holiday
Another season comes to an end, and Windletter is taking a break.
Creating content regularly, staying consistent, avoiding repetition, and, above all, trying not just to maintain quality but to improve it is no small effort.
Honestly, I’m reaching the end of this season running on fumes. So it’s time to disconnect, recharge, and gather strength to come back even stronger. Work is important, but so is rest.
That said, I won’t lie to you: during this break I usually take the chance to shape new ideas, think about future Windstories, and even write a few. Because the truth is, I enjoy writing and often find joy in the process itself.
There’s no shortage of ideas. In fact, many things come to mind that I could do beyond just writing, but time is limited, and Windletter, after all, is a side project. I put in many hours and a lot of care, but it remains just that: a project I juggle alongside everyday life.
The return is planned, most likely, for the first week of September.
📊 Some figures
Windletter continues to grow. We’ve now reached 3,000 subscribers in the Spanish edition and are getting close to 2,000 in the English version.
Growing a mailing list is no easy task, so I’d really appreciate it if you could recommend Windletter to friends, colleagues, or anyone who might find it interesting. Word of mouth is still, without a doubt, the best way to keep growing.
This season, quite a bit of effort has also gone into the LinkedIn account (basically, my two hands 😂), with truly spectacular results. The strategy has been simple: posting a summary of each Windletter news item there as well. And the results speak for themselves: we’ve already surpassed an impressive 11,000 followers.
From time to time, interesting debates even arise in the comments section of the posts. As a fun fact, Sven Utermöhlen, CEO of RWE Offshore, recently joined the conversation in one of them.
🤝 Sponsors
I’d also like to take this opportunity to once again thank our main sponsors, Tetrace, RenerCycle, and Nabrawind, whose support makes Windletter possible.


From here, a heartfelt thank you for the trust and for supporting the project.
🌴 Holidays
