SendGrid hit me with a $3,000+ overage after an old compromised API key started sending spam. This all occurred in the span for 4 hours while I was asleep. My normal bill is ~$21/mo on the 50k plan.

They didn’t stop sending at the plan limit and just kept billing.

I manage website contact forms for multiple client sites, so I’m looking for either:

• One account that supports isolated client/API key limits
• Or a cheap transactional email service with hard caps (reject/stop sends at limit, no surprise overages)

Main priorities are high deliverability and hard spending limits.

What are you guys using?

Please help!
