Master Inbox SDR-as-a-Service responds to every lead, qualifies prospects, and keeps conversations moving so your outbound actually turns into meetings.
Your Campaigns Are Working. Your Clients’ Follow-Up Isn’t.
We handle replies, qualification, and scheduling inside Master Inbox so leads don’t die in unattended inboxes.
Outbound Doesn’t Fail From Bad Leads. It Fails From No Follow-Up.
Our SDR team responds to every prospect so interest turns into booked calls instead of cancellations.
The #1 Reason Agencies Get Cancelled: A Prospect Replied and Nobody Answered
We respond, qualify, and schedule on your behalf so leads turn into meetings instead of churn.
What Reply Coverage Actually Handles For You
Clean, clear, and instantly communicates: this is human operational work, not software. We monitor replies, respond to prospects, qualify interest, and move leads toward meetings so results don’t depend on your client remembering to follow up.
Handled For You
Leads Never Sit Unanswered
Every new prospect reply gets a same-day human response. No more 12-hour delays, forgotten inboxes, or prospects moving on to a competitor while your client is “busy”.
As soon as someone replies, we take over the conversation and stop unnecessary follow-ups. Your campaigns stay professional and your client’s brand stays clean.
We qualify the prospect and either introduce your team or send the booking link. No more “what should I do with this lead?” moments that kill momentum.
We handle questions, objections, and hesitation so prospects don’t disappear after the first reply. Conversations continue until they book or clearly decline.
When replies are handled properly, prospects actually move forward. This prevents the most common agency churn: leads replied, nobody followed up, and the campaign got blamed.
Join a 20–30 minute kickoff call where we learn: • who you target • what you sell • how you want leads handled
You don’t need scripts or documentation prepared we guide the conversation.
We Train Your Dedicated Reply Team
After the call, we build your response playbook.
We define: • tone of voice • qualification criteria • objection handling • meeting routing
Your SDR team now knows exactly how to represent you.
We Handle the Conversations
We configure Master Inbox and begin monitoring replies.
From this point forward: • we respond to prospects • we qualify leads • we follow up manually • we book meetings or introduce your team
You just watch your calendar fill.
Social Proof & Case Studies
People have seen real results since using Master Inbox. These stories show what changes when you combine a Master Inbox with a dedicated reply team!
Our cold email process used to be messy. Responses were forwarded around and often hard to track. With MasterInbox, we have completely streamlined it. The Slack integration has also been a huge win, giving us instant lead notifications and improving our reporting.
Alex, Freedom For Founders.com
Running outbound campaigns on LinkedIn and email was a huge pain, and the LinkedIn inbox itself is too unreliable for keeping track of conversations. Master Inbox allows us to bring replies together and be much more nimble as an agency. We've basically onboarded more clients!

Conversation tagging & organization in Master Inbox
No. Every account is trained based on your kickoff call, your offer, and your positioning.
We follow your tone, your messaging style, and your qualification criteria. Conversations are handled conversationally and naturally not scripted.
They are speaking with a member of your team.
We represent your company and communicate as part of your organization. We don’t mention Master Inbox or present ourselves as a third party service.
We handle early-stage sales conversations after a prospect replies:
• responding to messages • asking qualifying questions • handling basic objections • manually following up • booking meetings or introducing your team
You still run outreach and close deals we make sure interested prospects don’t disappear.
No.
We do not write sequences, send cold emails, manage sending tools, or perform prospecting. This service starts once a prospect replies.
Yes.
If a prospect stops responding mid-conversation, we will manually follow up to keep the conversation moving toward a meeting or a clear yes/no outcome.
(Subsequences or campaign automation are not included.)
Yes.
You choose one of two options:
• We introduce you and hand off the conversation • We send your scheduling link and let the prospect book
We monitor and respond:
Monday – Friday 8:00 AM – 4:00 PM Eastern Time
Replies received outside these hours are handled the next business day.
Great that means your outreach is working.
We’ll notify you and offer additional coverage capacity so response times and conversation quality stay high. We will never silently ignore replies.
Very little.
You’ll join a short kickoff call and provide: • your offer • your target customer • how you qualify leads • your calendar link or handoff contact
We build the rest.
No.
This is not a contractor you supervise.
You don’t assign tasks, review activity daily, or manage schedules. We operate independently and escalate only when needed.
We assign trained staff to your account and build a response playbook specific to your business.
The minimum term ensures stable coverage and consistent lead handling rather than temporary onboarding.
You can pause outreach, but coverage time is still allocated to your account during the commitment period. The service is staffing based, not usage based.
No but agencies benefit the most.
Agencies typically use Reply Coverage to prevent client churn when clients fail to follow up with leads. Founders and internal sales teams use it to avoid living inside their inbox all day.
CRMs track leads. They don’t respond to them.
Most outbound pipeline is lost in the hours after a reply, not in the CRM stage. This service ensures every interested prospect actually gets handled.
Same business day during coverage hours, often much faster depending on volume. We have internal SLA's set up for 15 minutes.
Speed to response dramatically increases meeting booking rates that’s what this service is designed to protect.
Because dedicated staff is allocated to your account, the service requires a 4-month (or 6-month bundle) minimum commitment.
Most outbound campaigns don’t fail because of targeting or copy.
They fail because a prospect replied and nobody followed up in time.
Reply Coverage makes sure that never happens again.
