The email deliverability platform for GTM teams

You cannot forecast what you cannot see

Every GTM plan assumes a conversion rate on emails sent. Almost none of them account for the share that never arrived. When placement drops, the numbers move exactly like a market problem or a messaging problem, so teams rewrite sequences and hire reps to fix something neither will touch.

The signal is slow and misleading. Reply rates drift down over weeks, no bounce fires, no error appears, and by the time it is obvious enough to investigate you have lost a quarter of pipeline and spent the budget you would have used to fix it.

Warm-up gets sold as the answer. It moves one signal, early, and its effect fades exactly when your campaigns start mattering to revenue.

How Folderly protects your pipeline

01

Diagnose

We audit every layer that decides whether your email is delivered and tell you what share is actually reaching the inbox today. For most teams this is the first honest number they have had on a channel they already forecast against.

02

Fix

Your specialist works the root causes in priority order: authentication, damaged reputation, sending patterns, and the list quality that keeps re-triggering filters. Hands-on remediation, not a report your RevOps lead has to action between other jobs.

03

Monitor

Seed-based placement testing runs continuously, so a drop surfaces the day it starts rather than as a missed number at the end of the quarter.

04

Compound

Because reputation strengthens with consistent, well-managed sending, the channel gets more efficient as you invest in it. Your cost per meeting falls instead of quietly climbing.

What the platform covers

Authentication and DNS

SPF, DKIM and DMARC configured correctly and kept correct as domains, tools and vendors change. Misconfiguration here is the most common cause of sudden, total delivery failure.

Reputation monitoring and repair

Domain and IP reputation tracked across every major provider, with remediation the moment a signal degrades, so a bad month does not become a bad quarter.

Inbox placement testing

Seed-based testing gives you the number your forecast actually depends on: what share of sends reach the inbox, provider by provider, updated continuously.

Email validation

Validation that checks ESP-specific filters and email protection tools, not just syntax. Every invalid address you send to costs reputation and wastes rep time.

Blacklist monitoring

Continuous monitoring across the blacklists that affect B2B sending, so a listing is caught before it shows up in your numbers.

A named deliverability specialist

One person accountable for the outcome, so this does not become another thing your RevOps lead owns on top of everything else.

Who this is for

Roles

GTM, revenue and RevOps leaders

You own the number, outbound is a material input to it, and nobody in the business can currently tell you how much of it is reaching the inbox.

Company profile

Teams running outbound at real volume

Multiple reps, ten or more mailboxes, and a plan to increase sending this year rather than hold it flat.

Trigger

The forecast missed and the reason is not obvious

Sequences were rewritten, reps were added, targeting was changed, and reply rates still went the wrong way.

How this compares to setting it up once

Most tools help you get set up. What matters is whether anyone is still watching when your number depends on it.

GTM deliverability FAQ

How much pipeline are we actually losing to spam?
That is the first thing the audit answers. Most teams have never had the number, because sequencers report sends and replies but not placement. Across published Folderly case studies, teams arriving in crisis recovered an average of 70 percentage points of deliverability, which gives a sense of how much can be sitting unmeasured.
Our reply rates dropped but nothing else changed. Why?
That pattern is typical of a deliverability problem rather than a messaging one. Placement degrades gradually, no bounce fires and no error appears, so the decline looks like market softness or fatigue. The tell is that rewriting sequences does not move it.
Will this change how our reps work?
No. Folderly manages the infrastructure underneath your sending stack rather than replacing any part of it, so your sequencer, CRM and ESP stay where they are and your reps carry on as they are.
Should we fix this before hiring more reps?
Almost always, yes. Adding reps multiplies whatever your infrastructure is already doing, so if placement is weak you are buying more of a broken outcome. Teams frequently add headcount and watch pipeline stay flat for exactly this reason.
How long before we see results?
Diagnosis is fast, usually within the first days. Authentication and configuration errors can be corrected immediately, while rebuilding damaged domain reputation takes weeks, because reputation is earned through consistent sending rather than switched on.
What does it cost?
Pricing is per mailbox, so it scales with the size of your sending operation rather than with company headcount. The right figure depends on how many mailboxes you run and whether you need the audit or validation service alongside the platform.
Who owns this internally once it is running?
Your named specialist does. That is deliberate: deliverability usually lands on RevOps as an extra responsibility with no time attached to it, which is why it tends to be noticed late. Making someone external accountable is the point of the model.
