Trusted by growing teams across e-commerce, SaaS and agencies
Reach people where they actually read
Run email and messaging from a single contact profile, with consent tracked per channel and reporting unified across all of them.
Everything you need to grow a list and keep it
From the first opt-in to lifecycle automation and revenue reporting — without stitching five tools together.
Segmentation that updates itself
Custom fields, tags and live segments built on a filter DSL. Define a rule once and the audience recalculates as contacts change.
Regular, drip and A/B in minutes
Design once, test subject lines and content, schedule recurring sends and let send-time optimization pick the best moment per contact.
MJML editor with versioning
Responsive emails with reusable blocks, variables, automatic sanitization and a built-in spam-score check before you hit send.
AI subject lines & tone check
Generate subject options and catch an off-brand tone before sending, powered by a state-of-the-art language model.
Developer-first API & SMTP
Fire receipts, password resets and alerts over a fast REST API, gRPC or SMTP relay — the same deliverability as your campaigns.
White-label & sub-workspaces
Run client accounts under one roof with your own branding, isolated data and reseller billing rolled up to the parent.
Lifecycle flows on a visual canvas
Build trigger-based journeys on a drag-and-drop graph that reacts to product events in real time — welcome series, abandoned cart, win-back and everything between.
- Trigger on signups, product events, segment entry or a schedule
- Branch on attributes, engagement or A/B split
- Wait, send, update a contact, fire a webhook or call your API
- Stream product events in via API for a lightweight CDP
An inbox-first sending engine
Most platforms rent reputation. Climails runs its own MTA and gives you the controls that decide whether mail lands.
- Automatic DKIM signing with scheduled key rotation
- Guided SPF, DMARC, BIMI, MTA-STS and TLS-RPT setup
- Managed IP warmup with staged volume ramps
- Bounce and ARF/FBL classification, RBL monitoring and Google Postmaster insights
Know what every send earned you
Opens, clicks, conversions and revenue aggregated in a column store built for scale, with dashboards you can shape to your business.
- Real-time opens, clicks, bounces and unsubscribes per campaign
- Bot-filtered engagement so your numbers stay honest
- Custom dashboards and exportable reports
- Per-contact engagement scoring to find your best audience
Connected to the tools you already run
Sync customers, orders and events both ways — no engineering project required.
“We moved three tools into Climails and our inbox placement jumped within a week. The automations alone paid for the switch.”
