For Agencies

One burned client domain shouldn't end your retainer.

Agencies managing cold outreach for multiple clients carry multiplied deliverability risk. A single client domain burning can cascade into lost retainers, reputation damage, and months of inbox recovery work. SimplyWarmup gives your delivery team unified control over every inbox you manage.

The agency deliverability problem is worse than individual teams.

Individual sales teams manage one domain. Agencies manage dozens — often with different clients sharing infrastructure, varying send volumes, and inconsistent warmup histories.

When you're managing outbound for 15 clients, you need a system that removes the manual overhead of monitoring every sending domain while giving you the visibility to act before a client escalates.

SimplyWarmup's API-first architecture means your delivery team can provision and monitor inboxes programmatically — building client onboarding flows that connect new inboxes to warmup automatically from day one.

Agency-specific value

  • Centralised multi-inbox management
    All client inboxes visible from a single workspace. Health scores, pacing stages, and spam events surfaced without switching accounts.
  • API-driven client onboarding
    Use the REST API to automate new client inbox provisioning. Trigger warmup the moment a new domain is set up without any manual dashboard work.
  • Transparent, passthrough pricing
    At $19/inbox, agencies can pass through the cost directly to clients or absorb it into retainer pricing. No agency tier, no negotiation required.

FAQ

Questions from agency delivery teams

How do I manage warmup for multiple clients from one account?

All client inboxes are visible from a single SimplyWarmup workspace. Health scores, pacing stages, and spam events for every inbox are on one dashboard without switching accounts. For programmatic workflows, the REST API supports bulk inbox provisioning — connect new client inboxes and trigger warmup automatically as part of client onboarding.

Can I provision client inboxes via the API?

Yes. The REST API supports programmatic inbox provisioning. Build a client onboarding flow that connects a new sending inbox to warmup the moment their domain and DNS records are configured. This removes the manual step of logging into a dashboard and clicking through setup for each new client — particularly valuable at 10+ client scale.

Is there an agency volume discount?

No volume tiers, no negotiation. SimplyWarmup charges a flat $19 per inbox per month. This predictable pricing makes pass-through billing straightforward: include the per-inbox cost in your client retainer directly. An agency managing 50 inboxes pays $950/month total with no commitment.
