Multi-tenant email operations platform
Email to thousands, sent in seconds
Warm domains, manage providers, and track every delivery in one workspace. Built for teams that need control, real-time visibility, and deliverability while they scale.
Capabilities
Everything you need to send and land in inboxes
From warmup inbox pools and domain authentication to provider routing and live delivery telemetry, OppenMailer is built for deliverability, not just sending.
Domain warmup
Ramp up cold domains with controlled send curves, reputation-safe pacing, and warmup routines before you push serious volume.
Warmup inbox pools
Group inboxes into reusable pools for domain warmup, reply simulation, and reputation building without juggling separate tools.
Provider routing and failover
Route mail across SMTP, Resend, or SES with a single control plane and fallback paths when a provider or route turns unhealthy.
Authentication guardrails
Check SPF, DKIM, and DMARC before launch so teams fix trust issues early instead of discovering deliverability problems after a send.
Campaign pipeline
Build multi-step campaigns with scheduled sends, list segmentation, and automatic follow-ups from a single operational panel.
Inbox placement telemetry
Track delivery, opens, bounces, and reputation trends in one view instead of stitching together dashboards from multiple providers.
Workspace isolation
Every workspace keeps its own providers, lists, templates, quotas, and team access. Your sending operation stays separate by design.
Encrypted credential vault
Store provider credentials as encrypted secrets with role-aware access instead of passing raw keys around spreadsheets and chat threads.
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 prepare warmup inbox pools before you scale a new domain or sender.
Compose, launch, and monitor
Build templates, pick an audience list, schedule or send immediately, and track delivery plus reputation signals 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.
