What UniMailer is
UniMailer is a self-owned email marketing platform: you collect leads, organise them into mailing lists, segment them by behaviour, and send campaigns and automated sequences — all from infrastructure you control. Unlike rented social reach, your audience and your data stay yours.
The marketing job it does is simple to state and hard to do well: get the right message to the right person at the right time, and make sure it lands in the inbox. Everything below is a lever on that outcome.
- Own your audience — lists and data live on your own hosting
- Unlimited scale — lists, segments, subscribers, campaigns
- Multi-channel delivery — connect any SMTP or provider
- Built for marketers — templates, automation, reports
Grow
Build your audience
A list is a permission-based group of subscribers. You grow it with embeddable subscribe forms, import existing contacts by CSV or from an external database, and capture leads from your site or landing pages. Every list supports custom fields, so you collect the data your segments and personalisation will later depend on.
- Subscribe forms you embed anywhere
- CSV & database import for existing contacts
- Custom fields for richer profiles
- Double opt-in to protect reputation
Marketing tip: collect only the fields you will actually use to segment or personalise. A shorter form converts more visitors; you can enrich profiles later through behaviour.
Target
Segmentation
Segments are saved filters over a list — "opened the last campaign", "in the UK", "tagged VIP", "hasn't bought yet". Instead of blasting everyone, you send to the slice most likely to act. Tighter targeting lifts opens and clicks and protects deliverability, because engaged recipients signal to inbox providers that your mail is wanted.
- Behavioural — opens, clicks, activity
- Field-based — geography, custom data
- Tag-based — labels you apply in automations
- Reusable — save once, send to it repeatedly
Send
Campaigns & autoresponders
A regular campaign is a one-time send to a list or segment — a newsletter, a launch, an announcement. An autoresponder is a scheduled follow-up that goes out relative to an event (a set number of days after someone subscribes, for example), so new contacts receive your welcome series automatically, forever, without you pressing send.
- Regular broadcasts to lists / segments
- Autoresponders for welcome & drip series
- Scheduling for the right send time
- A/B testing of subject lines & content
Create
The content engine
Two editors, one clean rendering pipeline. The drag-and-drop builder gives you pixel-perfect, mobile-responsive layouts from reusable blocks. The simple rich-text editor is for founder-style, text-first broadcasts that feel personal. Both output lean HTML that loads fast and renders consistently across modern email clients.
- Drag & drop structural builder
- Rich text for authentic broadcasts
- Reusable templates & saved blocks
- Personalisation tags from custom fields
Automate
Marketing automation
Map a subscriber journey once and let it run. Triggers such as a tag being applied, a link clicked, a campaign opened, or a custom date start a flow; delays, conditions and actions branch each contact down the right path. This is how you nurture leads, onboard customers and win back the inactive — at scale, with intention rather than manual effort.
- Multi-trigger entry points
- Conditional branching on behaviour
- Delays & timing control
- Tag & field actions mid-flow
Land
Deliverability & sending
Deliverability is the whole game. UniMailer connects to any number of delivery servers — your own SMTP or providers like Amazon SES, SendGrid, MailGun, SparkPost and more — and can route volume across dedicated IPs for enterprise senders. Automated bounce handling and feedback-loop processing keep your lists clean and your sender reputation intact.
- Multiple sending servers & SMTP
- Dedicated IP options at scale
- Bounce & complaint auto-handling
- Domain authentication (SPF/DKIM) support
Marketing tip: warm new IPs and domains gradually and keep sending to engaged segments first — reputation is earned by consistent, wanted mail, not by volume.
Measure
Track & optimize
Every send reports opens, clicks, bounces, unsubscribes and complaints, with click maps and per-link detail. Use it to learn what your audience responds to, then feed that back into subject lines, timing and segments. What gets measured gets improved — and small, compounding lifts in open and click rate are where email ROI comes from.
- Opens, clicks, bounces in real time
- Click maps & per-link stats
- A/B test winners
- Exportable reporting
Protect
Compliance & hygiene
Permission-based sending is not just the law in many regions — it is the foundation of deliverability. UniMailer enforces one-click unsubscribe, honours opt-outs automatically, and monitors bounces and spam-trap hits so bad addresses are removed before they hurt you. Clean lists and genuine consent are what keep you in the inbox long term.
- Single-click unsubscribe on every send
- Automatic opt-out handling
- GDPR-friendly data ownership
- List scrubbing from live signals

Transactional email support means your product's receipts and notifications can flow through the same trusted infrastructure as your marketing.
