## Detailed recommendations

> **Building a SaaS and need receipts, welcome emails, and password resets**
>
> **Use Resend.**
>
> Resend is purpose-built for transactional emails with excellent deliverability and a clean developer API. It also works with Supabase SMTP, so you can route authentication emails (password resets, magic links) through Resend for consistent branding.
>
> **Pair with:** Supabase (auth) + Stripe (payments)
>
> ```plaintext wrap theme={null}
> Connect Resend and send a welcome email when a user signs up and an order confirmation after each Stripe payment.
> ```

> **Need high-volume email at scale (10K+ emails/day)**
>
> **Use SendGrid.**
>
> SendGrid handles high volume reliably and includes both transactional and marketing email features. It has robust analytics for open rates, click tracking, and bounce management.
>
> ```plaintext wrap theme={null}
> Connect SendGrid and send order confirmation emails with tracking links after each purchase. Include open and click tracking.
> ```

> **Want email marketing with newsletters and automated sequences**
>
> **Use Mailchimp or MailerLite.**
>
> Both are excellent for marketing campaigns. **Mailchimp** has more advanced features (A/B testing, complex automations, audience segmentation). **MailerLite** is simpler and more affordable, with a generous free tier.
>
> * Choose **Mailchimp** if you need advanced segmentation and A/B testing.
> * Choose **MailerLite** if you want simplicity and a free plan for up to 500 subscribers.
>
> ```plaintext wrap theme={null}
> Add a newsletter signup form to the footer. When someone subscribes, add them to Mailchimp and send a welcome email sequence.
> ```

> **Want email, SMS, and CRM in one platform**
>
> **Use Brevo.**
>
> Brevo (formerly Sendinblue) combines transactional email, marketing campaigns, SMS messaging, and a built-in CRM in one platform. It is the best choice if you want everything in one place without managing multiple integrations.
>
> ```plaintext wrap theme={null}
> Connect Brevo. Send a welcome email when a user signs up, then an SMS reminder if they have not logged in after 3 days.
> ```

> **Need SMS for verification codes or appointment reminders**
>
> **Use Twilio.**
>
> Twilio is the standard for SMS. Use it for verification codes, two-factor authentication, order updates, and appointment reminders.
>
> ```plaintext wrap theme={null}
> Add SMS verification to the signup flow using Twilio. Send a 6-digit code and verify it before creating the account.
> ```
