DevMail is the open-source newsletter & campaign platform built for teams who are tired of overpriced SaaS tools, platform lock-in, and deliverability black boxes. Own your list. Own your data. Own your revenue.
The existing market is dominated by expensive, closed-source platforms with poor developer experience and misaligned incentives. Here is exactly what is broken — and how DevMail fixes it.
Mailchimp, Brevo, and ConvertKit charge per subscriber. The moment your list grows, your bill explodes — even if you rarely send.
DevMail is free and open-source. No per-subscriber tax. Host it yourself or use our cloud — your list size never changes your cost.
Your subscriber list is trapped inside Mailchimp's export formats. Moving to a different provider means losing tags, segments, automation history, and engagement data.
DevMail keeps all your data in a portable, open schema. Export everything in standard formats. Switch providers in minutes, not weeks.
Substack and Ghost take 10 % of every paid subscription. At scale that's thousands of dollars you earned being redirected elsewhere.
DevMail never touches your revenue. Integrate your own payment stack — Stripe, Paddle, or anything else — and keep 100 % of what you earn.
Drag-and-drop editors look good in screenshots but break on mobile, strip your branding, and produce bloated HTML that lands in spam.
Send from clean, standards-compliant templates you own. Full HTML / MJML support, inline preview, and dark-mode testing built in.
Your campaigns mysteriously land in spam and the platform just says "check your content". No actionable insight, no domain health data.
DevMail surfaces domain reputation signals, bounce categories, complaint rates, and per-campaign inbox placement scores so you fix problems fast.
Adding email automation to your product means bolting on a 3rd-party SDK that forces customers through a separate login portal and exposes your subscriber data to a vendor.
DevMail ships a first-class REST API and webhook system. Trigger campaigns from your backend, sync lists from your database, and own every touchpoint.
Getting your sending domain properly configured — SPF, DKIM, DMARC, custom tracking links — requires reading five different blog posts and hoping nothing breaks.
DevMail's domain setup wizard walks you through every DNS record with live validation. Green checkmarks before you ever send a single email.
GDPR, CAN-SPAM, and CASL require documented consent, unsubscribe links, and data retention policies. Most platforms hide these behind enterprise plans.
Double opt-in, consent timestamps, automatic one-click unsubscription, and data retention controls are built into DevMail's free core — not add-ons.
From your first subscriber to your millionth send, DevMail gives you a complete toolkit — without hiding features behind enterprise tiers.
Rich HTML & plain-text editor, scheduling, per-list sends, and send-time optimisation.
Segments, tags, import via CSV / API, suppression lists, and merge fields.
Opens, clicks, bounces, unsubscribes, and complaints — per campaign and aggregate.
Step-by-step DNS configuration with live validation checks across all required records.
Customisable confirmation emails, grace periods, and audit-ready consent logs.
Full REST API, event webhooks, and an SDK-ready OpenAPI spec for integration.
Invite teammates with granular permissions — admins, editors, analysts, and read-only viewers.
Drip sequences, welcome flows, and re-engagement campaigns triggered by subscriber behaviour.
DevMail keeps the campaign creation flow simple, transparent, and safe — with checks at every stage before a single email leaves your domain.
Write in rich HTML, plain text, or import MJML. Preview renders across clients and dark mode.
Domain health check, link scan, spam-score preview, and subscriber list hygiene report run automatically.
Pick an exact time or let send-time optimisation pick the best window for each recipient's timezone.
Live open, click, bounce, and unsubscribe tracking. Exportable per-campaign CSV for every metric.
DevMail will be fully open-sourced under the MIT licence. Self-host on your own infrastructure, contribute features, audit the code, or run a fork. No artificial limitations, no “community edition” paywalls.
