The Mailgun alternative with honest pricing and zero complicated overage traps
Mailgun makes domain configuration confusing, locks features behind steep enterprise contracts, and charges punishing overage rates. SadaSend gives developers clear pricing, instant DNS verification, and native AI agent guardrails.
