Reloop vs turboSMTP

Reloop is an email delivery platform for transactional and programmatic workflows, available as hosted plans or self-hosted on infrastructure you control. It provides a transactional API and SMTP relay, plus webhook-based inbound routing and dedicated agent inboxes. First-party SDKs support Node.js, TypeScript, Python, Go, Rust, PHP, and Ruby; listed framework integrations include Next.js, Django, Ruby on Rails, and Laravel. Analytics cover delivery, opens, clicks, bounces, complaints, SMTP responses, and reputation. Templates support AI-assisted generation, editing, previews, variables, and version history. Hosted plans retain data for 45 days and set limits for inboxes, webhooks, and custom domains. The Free plan allows 3,000 emails per month and 100 per day; sending pauses when either cap is reached. Pro costs $10 a month for 50,000 emails per month, with overage at $0.50 per 1,000 emails. Self-hosting has no Reloop license cost, though server and delivery costs still apply. Reloop is open source under Apache 2.0 with Reloop Labs use restrictions.

turboSMTP is a cloud SMTP service for sending email messages and newsletters, with statistical analysis for individual and aggregate messages. Its SMTP API supports transactional messages such as login confirmations, welcome messages, and receipts from a website or app. The dashboard tracks clicks and opens in real time, while listed tools manage bounces, spam, and unsubscribes. Deliverability features include smart routing, custom tracking domains, and email validation before campaigns. An email marketing tool can design, send, and track campaigns using turboSMTP delivery infrastructure.

It offers a free plan allowing 200 emails per day for the first six months. Basic costs €14.95 a month for 15,000 emails per month; Pro costs €79.95 a month for the same send limit and up to 100 subaccounts.
