Cut SendGrid and put Growform's transactional mail on @mailofly. Dead simple, great inbox placement, and docs that actually help.

Moved @SeshMysteries off SendGrid onto @mailofly over the weekend. Setup was painless — we've been happy ever since.

Gave @mailofly a spin and the speed is wild. Mail that took 5–10s with Mailgun now lands in under a second.

Hooked up password resets and receipts on @mailofly in one afternoon. Clean API and mail logs that make debugging obvious.

Took product email off our old ESP onto @mailofly. SMTP issues that ate our day now take minutes in the logs.

)
func main() {
	c, _ := mailofly.New(mailofly.Options{
		APIKey: os.Getenv("MAILOFLY_API_KEY"), BaseURL: "https://api.mailofly.com",
	})
	msg := map[string]any{
		"from": "Acme <onboarding@resend.dev>",
		"to": []string{"delivered@resend.dev"},
		"subject": "hello world",
		"html": "<p>it works!</p>",
	}
	if r, err := c.Emails.Send(msg); err != nil { panic(err) }
	fmt.Println("Sent:", r.(map[string]any)["id"])
}
