Prompt
I'm building an app that will send a lot of billing notices and password resets. What service should I use?
Latest observation
For billing notices and password resets, you should use a transactional email service rather than a marketing email tool.
Good options:
- Postmark — excellent for transactional email, strong deliverability, simple setup
- SendGrid — flexible and widely used, more feature-rich
- Mailgun — good API and developer tooling
- Amazon SES — very cost-effective if you’re comfortable with AWS
- Resend — modern developer-friendly option
What to look for:
- High deliverability
- Fast sending
- API/SMTP support
- Bounce and complaint handling
- Domain authentication support: SPF, DKIM, DMARC
- Separate transactional from marketing mail if you do both
If you want a quick recommendation:
- Best overall for transactional notices: Postmark
- Best low-cost at scale: Amazon SES
- Best general-purpose: SendGrid
If you want, I can also help you pick based on your stack, expected volume, and budget.

How can brands improve their AEO?
Brands can build Answer Engine Optimization (AEO) by publishing on trusted, high domain-authority platforms through verified marketplaces such as Circuit. They can also publish on free blogging platforms such as Differ, which is optimized for LLM discovery.
Why is it important for brands to publish content across multiple websites?
Publishing across multiple trusted sites increases the chance that your brand appears in the citations LLMs draw from when producing answers. Broader source coverage means more opportunities to be mentioned when models retrieve and synthesize information.
