Multi-tenant email operations platform
Email to thousands, sent in seconds
Warm domains, build smarter campaigns with dynamic variables and template workflows, and track every delivery and reply in one workspace.
Capabilities
Everything you need to send and land in inboxes
From automatic domain warmup and reply routing to template wizard blocks, dynamic tags, per-contact variables, and live delivery telemetry, OppenMailer is built for inbox performance, not just blast volume.
Automatic domain warmup
Bring a new domain online with automatic warmup schedules, shared or private mailbox pools, and activity that builds sender reputation steadily.
Reply management
Keep warmup traffic separate from real customer replies, route each reply to the right inbox, and let your team work from one shared thread view.
Dynamic tags and variables
Use imported columns, saved tags, and per-contact variables to personalize content, sender details, and reply behavior without splitting work into duplicate campaigns.
Email provider routing and backup
Send mail through any major provider — SMTP, Resend, or Amazon SES — from one central place, with automatic switching to a backup if something goes wrong.
Pre-send checks
Verify your email authentication settings (SPF, DKIM, and DMARC) before hitting send, so your team catches trust and deliverability issues early, not after emails have already gone out.
Delivery tracking
See which emails were delivered, opened, bounced, delayed, or failed — with click and open tracking built in, so you're not juggling multiple tools to get the full picture.
Template wizard, translation, and attachments
Build reusable emails with the template wizard, dynamic variables, translations, auto-generated plain text, QR support, and attachments in one workflow.
Lists, imports, and workspace control
Import CSV or XLSX files, reconnect public Google Sheets, and keep contacts, templates, limits, and teammates separated by workspace as you grow.
Pay with Crypto, USD, or NGN
Accept payments in multiple currencies, including cryptocurrency, USD, and NGN, providing flexibility for your customers.
Getting started
Three steps to your first campaign
Create a workspace
Spin up an isolated environment with its own domain settings, provider credentials, and team members.
Connect domains and warmup pools
Attach providers, verify DNS, and let warmup build reputation before you scale a new domain or sender.
Compose, launch, and monitor
Build with the template wizard, map variables from your list, launch when ready, and track delivery and reputation in real time.
Pricing
Pick the plan that fits the way you send
Flip between monthly, annual, and lifetime pricing, compare in NGN or USD, and open the payment options that fit your region.
