Most apps need transactional email (sign-up confirmations, password resets, receipts) long before they need newsletters. Compare deliverability, how easy it is to send from your code, and the price at your volume.
Sending APIs: Resend, Postmark, Mailgun, SendGrid, Mailtrap and Amazon SES send through an API or SMTP. Amazon SES has the lowest price per email, and Mailgun lets you keep your data in the US or the EU. Cloudflare Email Service, in beta, sends from Cloudflare Workers.
Product email: Loops puts transactional, lifecycle and marketing email on one contact list and prices by contacts.
Templates: React Email and Maizzle turn React or Vue components styled with Tailwind CSS into email HTML that works in Gmail and Outlook.
Whichever you choose, set up SPF, DKIM and DMARC on your sending domain first, or your emails are likely to land in spam.
