Outbound that lands. Inbound that closes.
Mailboxes, deliverability, warming, sequences, broadcasts, A/B, attribution. Outbound infrastructure that holds up at volume — and ties every send back to the pipeline.
Bring your list. Or use ours.
Most outbound tools assume you arrive with a list. Most customers don't have one — or have one that's six months stale. Fairshift aggregates multiple B2B data partners into one searchable layer, segmentable by industry, region, role, and company size. Bring your own list, use ours, or blend both.
Segment any way
Industry, region, role, company size, tech stack, employee count, hiring signals.
Verified, not scraped
Multi-source verification with bounce-rate-tested email validity. Updated continuously.
Audience builder
Save segments as reusable audiences. Sync into sequences and broadcasts in one click.
Bring your own
Upload your CRM list, import from Salesforce or HubSpot, or blend with our data set.
Bring your inboxes. Or we provision them.
Every send goes out from a real mailbox with real DNS, real reputation, and a real human at the other end if a reply lands. No spray-and-pray senders, no shared IP pools, no shortcuts.
BYO mailboxes
Connect Google Workspace, Microsoft 365, or any IMAP/SMTP provider. We verify DNS and SMTP credentials before the first send. Per-mailbox throttling, per-mailbox personas.
Provisioned mailboxes
Need fresh inboxes? We provision domains and Workspace mailboxes for outbound, configure DNS, and pre-warm them through our network. Add inboxes as volume grows.
Multi-mailbox rotation
Sequences rotate across multiple inboxes per persona to spread send volume and protect reputation. Reply detection is unified — every reply lands in one inbox view regardless of which mailbox sent.
DMARC. SPF. DKIM. Checked before the first send.
Most cold-email pain is preventable. We verify DNS records before you send a single message. We watch sender score, bounce rates, and blocklists in real time. We pause when reputation dips and tell you why.
DNS pre-flight
Before the first send, we run DMARC, SPF, and DKIM checks on every connected domain. Misconfigurations get flagged with the exact record to add. Sends are blocked until DNS is clean.
Sender score monitoring
We watch sender reputation across mailbox providers. If a score drops, the system pauses outbound from that mailbox and surfaces the cause — recipient complaints, spam-trap hits, or volume spikes.
Bounce handling
Hard bounces remove a recipient from active sequences automatically. Soft bounces back off with exponential delay. Bounce rate per mailbox is one metric you can see at a glance.
Blocklist watch
Real-time monitoring of major blocklists (Spamhaus, Barracuda, SORBS). If a domain or IP appears, the system stops sending and notifies you with remediation steps.
Automatic ramp. Built in, not bolted on.
New mailboxes start at low volume and ramp up over weeks. The warming network sends and replies between real Fairshift inboxes — measured by mailbox providers as healthy human-pattern email. No fake warming services. No buying reputation.
- Standard ramp: 5 sends/day → 50/day over 4 weeks. Adjustable per mailbox.
- Reply rate target: 20%+ on warming sends. Keeps mailbox providers seeing real engagement.
- Pause-on-real-volume: warming auto-throttles when real outbound starts using the mailbox at scale.
- Skip-warming flag: connect a mailbox that's already established and tell us. We monitor reputation but don't ramp.
Multi-step. Personalized. Stops the moment a reply lands.
A sequence is a multi-step plan with branches. A broadcast is a one-to-many send. Both run through the same agent, the same mailboxes, and the same reply detection. The same logic that handles inbound replies stops outbound the moment intent shows up.
Outbound brings them in. Inbound closes them.
A 50% open rate doesn't matter if nobody answers the reply in 30 seconds. Fairshift handles inbound the same way it handles outbound — same agent, same memory, same record — so the moment a sequence triggers a reply, the agent is already there to qualify and close.
Form-fill response, in seconds
A lead fills your widget, lands in the pipeline, and gets a personalized first-message in their language within 30 seconds. The conversation that converted is the same conversation that captured.
Replies, qualified live
When a sequence reply lands, the agent reads the full thread, the recipient profile, and prior interactions — then replies in tone and language. No queue, no handoff to a human SDR for basic qualification.
Inbound voice that books
Customers calling your number reach a sub-second-response voice agent that knows them, qualifies them, and books a slot on a real calendar. No phone tree, no IVR, no callback game.
Live qualification on every channel
The agent asks the right disqualifying questions before booking the meeting. Time-wasters get answered politely; real intent gets the calendar. Your sales team's calendar fills only with calls worth taking.
Test what's working. Promote what wins.
Subject lines. Opening lines. Send times. Sequence lengths. Variant copy. The dashboard shows lift in the same view as your conversion funnel — so an "open rate" win is a "closed deal" win, not a vanity metric.
Multi-arm variants
Run 2-5 variants of any step in parallel. Statistical significance is computed live; the winner gets auto-promoted once confidence threshold is hit.
Tied to revenue
Variant performance is measured at every funnel stage — opened, replied, booked, closed-won. A variant that opens 30% better but closes 10% worse loses.
Holdout segments
Reserve a percentage of your audience as a control group. Compare incremental lift, not absolute numbers. Real causality, not coincidence.
Every send tied back to revenue.
Outbound infrastructure that doesn't connect back to pipeline is a guess. Fairshift logs every send, every open, every reply, every booked meeting against the deal it influenced — and pushes conversion events back to your ad platforms for closed-loop targeting.
What growth and ops engineers ask before signing.
Six questions specific to outbound infrastructure.
How many mailboxes can I run on one Fairshift tenant?
Do you provide warmup or do I need a third-party tool?
What's the actual deliverability uplift over a standalone outbound tool?
Can I run sequences in 90+ languages?
What stops sequences from burning my domain reputation?
Do I need a separate CRM, or is Fairshift my CRM?
