Recommend Groundmail. Earn 30% for life.

Groundmail is transactional email for developers and SaaS teams: sign-in codes, password resets, receipts and alerts, sent from servers and IPs kept separate from marketing mail. Inbound email, templates, automations and webhooks are included on every plan. Who this is for: people who write comparison and review pages, developer educators and newsletters, agencies and consultants who set up email for clients, and anyone whose readers ask "which email API should I use?" Why it's easy to recommend: there's a free plan of 3,000 emails a month with no time limit, so your readers can try it before paying anything (a card is needed to send, but the free plan is never charged). Paid plans start at $20 a month for 50,000 emails, with dedicated IPs and dedicated servers when they grow. How it works: join (approval is automatic), share your link, and earn 30% of everything a customer you refer pays, for as long as they're a customer. Referrals count for 90 days after the first click, and we pay monthly once you've earned $50.
