Prompt
What's the cheapest transactional email service?
Latest observation
“Cheapest” depends on volume, region, and whether you need API only or SMTP + deliverability features. But in practice, the lowest-cost options for transactional email are usually:
Often cheapest at very low volume
- Amazon SES
- Very low per-email pricing
- Good if you can handle some setup complexity
- Best for sending lots of emails cheaply
Usually cheapest/easiest for small apps
- Brevo (Sendinblue)
- Free tier, then relatively low pricing
- Good UI and API
- Mailgun
- Competitive pricing, developer-friendly
- Postmark
- More expensive than SES, but excellent deliverability and simplicity
If you already use a cloud provider
- AWS SES is typically the cheapest overall
- Google Cloud / Azure don’t really have a direct transactional email product as cost-effective as SES
Rule of thumb
- Absolute lowest cost: Amazon SES
- Best balance of price + ease: Brevo or Mailgun
- Best deliverability + transactional focus: Postmark
If you want, I can compare actual monthly costs for your expected email volume (e.g. 10k, 100k, 1M emails/month).

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 dotdotPR. 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.
