Leadpush

What Leadpush is

Leadpush is an email platform, run by LeadPush, LLC, that puts transactional email and marketing email in one product. Its homepage headline is "Transactional + Marketing Email. One Platform.", and the company describes the aim as to "modernize your email stack with first-class tools for transactional delivery, lifecycle automation, and every message in between." Developers send product-triggered mail such as password resets, one-time passcodes, receipts and alerts through an API, SDKs or an SMTP relay. Marketers build newsletters, lifecycle campaigns and automations in the same account, working from the same contacts and events.

The idea that ties it together is a shared record. Under "Connected Timeline" the site says Leadpush lets you "tie application-generated and marketing emails to the same contact record and event stream", and under "Delivery Control" that decisions about what to send and how to send it happen together. A SaaS team, for example, can see a user's verification emails and onboarding campaign on one timeline instead of in 2 tools.

For developers

The developer pitch is speed: "Send transactional email with SDKs, REST APIs, or SMTP relay in minutes. Leadpush gives developers a fast path to production for password resets, OTPs, receipts, and alerts without adding complexity to the stack." The SMTP relay is aimed at existing systems, with the line "Move existing systems onto dependable SMTP delivery without extra complexity", and the transactional API is described as sending product-triggered emails "with reliable APIs and delivery controls."

The SDK page lists the official libraries and their status. The Node.js SDK (@leadpush/sdk-node, for TypeScript and JavaScript on the server), the Python SDK (leadpush, for synchronous or asynchronous applications) and the PHP SDK (leadpush/sdk-php) are marked "Available now". The Go SDK (github.com/LeadPush/leadpush-go) is marked "Coming soon", and Ruby, Java and .NET are listed as planned but not available yet. Developers who do not want an SDK can call the API directly.

Setup on the Node.js page takes 4 steps: install the package with npm, pnpm or yarn, set the API key in your environment or a secret manager "so it never ships to browser code", create a shared client, and send the first email from a verified workspace sender, keeping the returned message identifier for delivery troubleshooting. Beyond sending, the SDKs manage contacts, events, fields and suppressions. The page highlights fully typed APIs, event capture, helpers for custom fields, suppression helpers that keep opt-out and delivery exclusion logic close to your application, pagination helpers for large result sets, and direct API requests for newer endpoints. Errors come back as typed exceptions for authentication, validation, timeout, missing resource and unsupported endpoint cases.

For marketers

On the campaign side, the homepage says marketers can "plan, launch, and improve newsletters and campaigns with the audience targeting, follow-up, and reporting tools lifecycle teams use every day." Campaigns target segments tied to engagement and customer behavior, follow-up sends launch from signup, purchase and lifecycle activity "without manual list work", and performance tracking sits in the same workflow. The site names 4 popular lifecycle use cases: welcome emails, onboarding emails, trial expiration emails and win-back emails.

The campaign builder shown on the homepage works in stages (draft, simulate, publish) and branches a newsletter into follow-ups depending on whether a recipient opened it. The Insights panel beside it covers best send window, an A/B test winner by subject line and revenue lift, so A/B testing is part of the product.

Segmentation is built from customer profile, event and message data. The audience builder creates dynamic audiences from people, events and attributes with no exports required, refreshes them continuously as new events arrive, and supports nested AND/OR logic. The example segment on the page, "High Intent Shoppers", combines product viewed in the last 7 days, added to cart in the last 7 days and no completed purchase, and feeds a cart reminder email. Segments can be used in email campaigns, A/B tests, automations and transactional sends.

Templates and design

The Template Studio is a drag-and-drop editor with a block library (hero banner, product grid, image and text, call-to-action button, divider), desktop, tablet and mobile previews, and conditional logic on rows. The site lists "visual blocks for hero, product grids, CTAs, and content modules", "dynamic tokens and logic rules for contact-specific personalization" and "desktop and mobile preview modes before every send." Dynamic personalization uses "live traits, events, and conditions to tailor every message", and a Template and Brand Studio lets a team create reusable components and lock in brand rules.

Deliverability

Leadpush gives deliverability its own section. It tracks "mailbox provider performance, sender health, and delivery outcomes across transactional and marketing email", with delivery monitoring by mailbox provider, reputation alerts that let you adjust routing, cadence or targeting before problems grow, and protection controls built on suppression, policy safeguards and reputation-aware logic. Deliverability controls let teams monitor and tune routing, reputation signals and sending behavior as volume scales. The homepage also lists "Global infrastructure", described as resilient delivery systems built for growing send volume.

Pricing, privacy and support

The site links to a pricing page from the header and footer, and offers "Get Started" and "Create Account" buttons. On data handling the homepage says "Privacy first. Customer data stays governed across product and campaign workflows", and the footer links to terms, privacy, data processing and acceptable use and anti-spam pages. Support is described as "Expert support. Real guidance when teams need help with delivery or strategy", backed by a support center, a knowledge base, API documentation, the SDK directory, GitHub repositories and a system status page.

Who it suits

Leadpush suits SaaS companies and product teams that send both kinds of email and are tired of running a transactional provider and a marketing tool side by side. Developers get typed SDKs for Node.js, Python and PHP, a REST API and an SMTP relay; marketers get segments built on live events, lifecycle automations, A/B testing and a block-based template editor, all on the same contact record. Teams on Go, Ruby, Java or .NET should check the SDK status first, since those libraries are still coming. A solo newsletter writer will find more developer tooling here than they need.
