Best Email Marketing Tools for Coolify Users

Overview

Coolify makes self-hosting a sending stack almost trivial: you deploy a service, point a domain, and you own the box. But "email marketing tools for Coolify" really splits into two different jobs — the sending layer (the API/SMTP that actually delivers mail) and the workflow layer (campaigns, a reply inbox, templates, drafts, analytics). Coolify's one-click catalog covers the first job well and barely touches the second.

This guide walks the tools that genuinely fit a Coolify box, what each is good at, and the DNS and deliverability work none of them remove. Mailbase is included honestly: it is not a sending tool you deploy on Coolify — it is the workflow layer you point at a Coolify-hosted useSend instance for €5/month, or run on managed sending if you would rather not host anything.

The sending layer you deploy on Coolify

These run as services on your Coolify instance and do the actual delivery. They are cheap to run because you only pay for the server plus whatever upstream relay you use (commonly AWS SES). They do not give you a campaign UI or a shared inbox out of the box.

useSend (formerly Unsend) is the closest fit for most builders: an open-source, API-first sending platform with a dashboard, a Resend-style API, and domain/API-key management. It is widely self-hosted on Coolify and pairs cleanly with AWS SES for the underlying delivery.

• useSend — open-source Resend-style sending API + dashboard, SES-backed
• Listmonk — fast self-hosted newsletter and mailing-list manager (single binary)
• Mautic — heavier open-source marketing automation if you need full campaigns + automations
• Plunk — open-source transactional + marketing platform with pay-as-you-go pricing

The DNS and deliverability work nothing removes

Self-hosting the sending tool on Coolify does not change the fundamentals of getting into the inbox. Whichever tool you pick, you still configure SPF, DKIM, and DMARC on your sending domain, handle bounces and complaints, and respect unsubscribe requests.

If your tool sends through AWS SES, you also move the account out of the SES sandbox and wire up bounce/complaint notifications (SNS) so suppression works. This is the part that bites teams who assume "self-hosted" means "plug and play."

• SPF, DKIM, and DMARC on the sending domain
• SES sandbox exit + SNS bounce/complaint handling (if SES-backed)
• Suppression list so bounced/complained addresses are not re-mailed
• Compliant one-click unsubscribe

The workflow layer Coolify leaves out — and where Mailbase fits

Coolify's catalog gives you sending, but a team still needs the layer above it: a shared reply inbox, AI-assisted drafts, MJML campaigns, A/B testing, scheduled sends, analytics, and a developer API. Stitching that together from open-source parts is real work.

Mailbase is that workflow layer. On the bring-your-own useSend plan (€5/month) you point Mailbase at a useSend instance you host on Coolify, so delivery stays on your infrastructure while the team gets the inbox, campaigns, and AI tooling. If you would rather not host anything, the same workflow runs on Mailbase managed sending — free for 200 emails/month, or €9/month for 50,000.

• Shared reply inbox + AI-assisted drafts
• MJML campaigns, A/B testing, scheduled sends, analytics
• REST API and signed webhooks
• BYO useSend at €5/mo (your Coolify box delivers) or managed sending from free

Common mistakes

• Comparing headline price instead of total operating cost (seats, sending, workflow).
• Paying for a broad suite when you only need the operating layer.
• Ignoring per-seat or per-contact scaling costs that bite later.
• Assuming self-hosted is free — server, SES, DNS, and monitoring still cost.
