Most companies don't need to evaluate every product at once. They come to us with a specific situation — and the right tier depends on that situation.

Senders has a layered product line. At the top, Senders.ai handles AI-powered campaign planning, sequencing, and sending for individuals and small teams. From the Business tier upward, Senders.co Managed Email Infrastructure begins — production-grade sending infrastructure provided alongside the platform. The Deliverability Dept. tier adds a dedicated Deliverability Engineer and the full monitoring suite. The 90-Day Outbound Sprint is a parallel, full-service offering for companies that want Senders to operate outbound end-to-end.

Here's how to decide where to start.

You Want Pipeline but Don't Have the Team to Run Outbound

Start with the 90-Day Outbound Sprint.

This is the right fit if:

• You need outbound producing results, but don't want to build the internal function.
• You're a founder-led or lean growth team that needs pipeline now.
• You're hiring SDRs but the seat won't be filled for months.

What the Sprint includes:

• A dedicated Account Strategist who runs the program: audience building, data sourcing, campaign construction, copy, testing, iteration.
• Managed Email Infrastructure underneath: aged domains, pre-warmed IPs, controlled DNS, continuous monitoring.
• Minimal team involvement — your role is strategic direction and follow-up (under one hour per week).
• Everything we build is yours: audiences, campaigns, copy, data. After Day 91, you can continue the Sprint or transition to a self-managed tier and we hand back the Apollo account.

Your Team Can Run Campaigns, but the Sending Layer Is the Problem

Start with the Business tier.

This is the right fit if:

• You have an internal team or agency running campaigns, but deliverability is degrading.
• Email volume can't scale because of IP throttling, domain reputation loss, or unexplained bounce rates.
• You're using Apollo, Outreach, Salesloft, Instantly, or similar and want production-grade infrastructure underneath those tools.

What changes with the Business tier:

• Keeps your existing sequencer tools. Senders.co provides the SMTP layer underneath.
• Professionally managed sending: aged domains, pre-warmed IPs, tight authentication, continuous monitoring.
• Self-serve full-company monitoring suite covering up to 5 domains and 5 email sending systems.
• The Deliverability Optimization Stack runs behind every send — warming, pre-send verification, intelligent ramp-up, content safety scanning, and more.

Your Deliverability Problem Needs a Dedicated Engineer

Start with the Deliverability Dept. tier.

This is the right fit if:

• Deliverability has dropped and your team can't explain why.
• You inherited a sending setup that seems unhealthy across multiple domains or sending systems.
• A migration went sideways and recovery has stalled.
• You operate at a scale where small problems compound fast and you need someone watching continuously.
• You need an independent audit of email authentication and inbox placement posture.

What the Deliverability Dept. tier includes:

• A dedicated Deliverability Engineer who actively monitors, interprets, and acts on the data.
• The Q1 intensive in the first quarter: full audit across all domains and sending systems, crisis response (DNS fixes, reputation recovery, blacklist remediation), setup of all ongoing testing and monitoring, infrastructure buildout, and backup-domain setup.
• The full Deliverability & Monitoring Suite covering up to 10 domains and 10 email sending systems — including ad-hoc seed-list testing, proactive alerting, and dedicated incident response (the three things the Business-tier suite doesn't include).
• Managed Email Infrastructure included (1 sender at 600 emails/day).
• Dedicated Slack channel and ad-hoc meetings.

Evaluating From an IT, Security, or Operations Perspective

• Continuous governance, multi-domain oversight → Deliverability Dept.: dedicated engineer, full monitoring suite, ad-hoc seed testing, proactive alerting, and dedicated incident response.
• Production-grade sending without dedicated engineering oversight → Business tier: same infrastructure layer, self-serve monitoring covering 5 domains and 5 systems, email + Slack support.
• No sending need yet, just planning and sequencing → Single or Team tier on Senders.ai with Bring Your Own Mailbox.

Not Sure Where the Constraint Is?

Most companies aren't sure.

• A conversation with our team helps determine what fits.
• Sometimes one tier covers it, sometimes a Sprint runs in parallel.
• Sometimes nothing fits yet — and we'll tell you.

Design principle:

• Each tier delivers value independently.
• Transitions are clean: you can upgrade or downgrade as your needs change, and engagements that include Managed Email Infrastructure share the same underlying stack.

Common Progressions We See

• Sprint → Business or Deliverability Dept.: Start with full-service execution, hire SDRs, transition campaigns in-house, keep the managed infrastructure running underneath.
• Business tier → Deliverability Dept.: Start on self-serve infrastructure, discover the operation needs continuous engineering attention, upgrade to the dedicated engineer.
• Deliverability Dept. → continued: Solve the immediate crisis in Q1, then continue on the ongoing rate ($1,200/month) for continued monitoring and engineering oversight.

None of these paths are mandatory — they're just patterns we see.

The Short Version

• Need pipeline without building internal operations? → 90-Day Outbound Sprint
• Have a team running campaigns but the sending layer is the bottleneck? → Business tier
• Need a dedicated engineer for a complex or multi-domain deliverability operation? → Deliverability Dept.
• Just planning campaigns with your own mailbox? → Single or Team tier
• Not sure? → Talk to our team

Every engagement starts with a conversation — not a pitch deck or a demo. We figure out what fits, and if nothing fits, we tell you.
