Reevaluate using SendGrid for sending release announcement emails

[xmudrii]

What would you like to be added:

Lately SendGrid hasn't been very reliable for sending release announcement emails using krel announce

We're often facing problems such as:

• Emails not getting delivered to all mailing lists (lately they're getting delivered only to k-announce)
• Folks having random issues with their SendGrid account
• SendGrid deactivating account after some time of inactivity requiring a new account to be created

We should consider:

• If we can fix those issues with SendGrid
• If there are any other offerings that provide better user experience for our use case

Why is this needed:

It's important that the Release Managers can reliably send release announcement emails after cutting releases as many end users and Kubernetes developers depend on these emails.

AWS Simple Email Service looks like a great alternative.

I mentioned in Slack, but for record, I plan on seeing how challenging it would be to implement using a Google app password - which could be a good bridge to using a more robust approach (SES/group sending/etc). I'm reluctant to assign myself if others want to look at a more permanent approach - but keep me in the loop please!

I'm in favor of switching to something more suitable :+1:
