Wordpress Site Title - How does it affect SEO

Hi guys, here is the situation im in.

Jetpack is pulling my site title and using it as the 'from' when sending out emails each time i publish a new post.

I need to change this 'from name' so im going to have to change the site title. I currently rank #1 for my term. I have a page created, and I use that as my homepage (not a typical blog feed).

So my home page (which is a page) has the meta title of (ALL OF THIS IS JUST AN EXAMPLE)

Keyword Ranking #1 = Best Cat Grooming Tips

URL
Catcaregalore.com

Homepage (Which is a page) Meta Title
Best Cat Grooming Tips - Cat Care Made Easy

General Settings > Page Title
Best Cat Grooming Tips

I need to change the General Settings > Page Title to:
Cat Care Galore

This will mean that when subscribers receive an automated email when i publish a new post it will appear from the sender name Cat Care Galore

(I am having to change this due to an affiliate partner changing their T&C's)

Will this affect my SEO & rankings in anyway?

If so, how can i change the 'from sender' name to something that is not the General Settings > Page Title name?

Thanks

Having the site title as the From line in an email system is very restrictive. Yes it's going to have some impact on your SEO if you change all titles, but we can't say it's gonna be bad. Anyway this email system you're using should be more configurable, perhaps you can edit the PHP plugin and get it to send a different From line.

It is the Jetpack plugin im using. Tbh, im surprised that there is no other way to change it (at least I can't find one from Googling)

Any suggestions?
