Do I need to know in an email from a major cycling organisation based in Manchester that was signed off as :
<Redacted : very obviously a female name>
(She/Her)

Pronouns in a signature doesn't do any harm if it isn't useful or pertinent. Maybe it's not ideal for using on external emails but I don't think Outlook lets you auto set signatures by domain of TO: field.
It's a way of showing solidarity with trans people or those whose names aren't so obviously gendered or genderable... Think Andrea is an Italian mans name but would be read as female in the UK. Adrian in the USA can be female whereas in the UK it is always
female. Alex could be either of the binary genders. Non binary people don't always have gender neutral names.
Some trans people have names or physical appearance and clothes choices that don't necessarily code their gender to other people by default. Choice to share pronouns in signature is one way they can let people know what the correct ones are.
I have email pronouns in my work signature. I hope to be an ally to trans people and show that I will be kind and decent to them. I have worked with several trans students and it has been helpful when I've found mixed names in paperwork from them to receive an email with "my pronouns are XYZ" cos that usually explains it without me having to ask "I notice different names, can I check which name/pronoun is correct for you please?".
Knowing a student's pronoun means I can use it correctly to them and is an opportunity to ask if they need advice on navigating university as an often young trans person. Not everyone knows how to change their name in the systems, that MyUni has a process for doing name/pronoun change for different levels of stuff and staff should treat that trans student with dignity and respect. Just as we look out for other things like caring responsibilities or other signs of needing support that the wider uni could provide.
For what it's worth, I don't believe anyone should be compelled to disclose pronouns in verbal or written contexts, it should always be optional with no censure for not doing so.
