Billing Email concerns

I have a notice regarding payment and request for updated credit card information.
The email does not match the pricing disclosed and the address in the email seems SPAM, yet there is also a "banner" message on my text blaze home page.
Thoughts desired, and advice on how to proceed appreciated.

Hi Lisa,

I just replied to your email into Support, let's resolve this question via that email since it's billing related.

Hi @lgreenaker ,
Welcome to the forum.

Text Blaze Pro is $2.99 a month when billed yearly (see screenshot below). $2.99 * 12 months = $35.88 a year.
You can also subscribe to a monthly plan, which is $3.49 a month. In which case, you'll only be charged $3.49 every month.

What about the address seems spammy?
