Reputation, by design

Why your sender
reputation matters.

Shared infrastructure rewards everyone when it’s clean — and punishes everyone when it’s not. We chose strict.

We vet every customer

Bad actors hurt everyone on shared IPs. We screen new customers carefully so the platform stays clean — and your emails stay deliverable.

AI scores every send

Our AI analyzes every campaign before it goes out, flagging spam triggers and content that could damage your reputation.

Real-time monitoring

Track delivery rates, opens, bounces, and complaints across every domain. Catch problems before they spread.

Our approach

Why we built this.

PristineSend was built by email industry experts who got tired of explaining bad results caused by bad IP reputation. Most platforms let anyone in, charge you to send, then charge you again to clean your list. We do it differently:

  • •We vet every customer before they send
  • •We verify your list every month — worst-risk contacts first, until the whole thing is clean, then we keep it that way. Automatically, included in your plan.
  • •We monitor every campaign and protect you from yourself when things go wrong

Your sender reputation isn’t a feature. It’s our entire product.

Built for the agent era

Your AI agent writes the email.
We make sure it lands.

Connect your AI agent and it can run the whole job — write the campaign, check it’ll reach the inbox, build the audience, and send it. Every other platform has an API; none was built for an agent to drive — with a deliverability check and safety rails on every step.

01

Write

Your agent drafts the campaign from a prompt — subject, body, the whole thing.

02

Check it’ll land

It runs a deliverability check before anything goes out, and fixes what would trip spam filters.

03

Build the audience

It turns a plain-language filter into a segment — and you see exactly who’s included.

04

Send — you approve

It queues the send. Nothing reaches your list until a human clicks approve.

Safe by construction. The high-stakes steps — sending to your whole list, creating an audience — sit behind explicit permissions and a human approval. So an agent can do email end to end without ever risking your sender reputation.

For developers

Built on MCP. One command to connect.

It’s a Model Context Protocol server — works with Claude Code, Cursor, and the Claude API. Install the plugin, point it at your workspace with a scoped key, and start sending deliverable email from your agent.

Built-in, not bolted on

How we keep
your list healthy.

No plugins, no integrations, no extra fees. List hygiene is part of the platform.

Free monthly verification

Every plan includes automated verification of your highest-risk contacts. We catch the bad emails before you ever hit send.

Live bounce protection

We watch every campaign in real time. If bounce rates start climbing, we pause sending automatically and tell you exactly what to fix.

Spam trap detection

Spam traps can destroy your sender reputation overnight. We detect them and quarantine them before they touch your domain.

Unlimited campaign sends

Send as often as your audience wants to hear from you. No monthly email caps. You own the frequency — we handle the infrastructure.

Our standards

What we won’t allow.

We turn away senders whose practices would contaminate the shared reputation of everyone on the platform. This isn’t gatekeeping for its own sake — it’s how we keep your emails out of spam.
