Cladiant + Plusvibe
Provisioned, authenticated mailboxes ready in your Plusvibe workspace.
Plusvibe is a cold email sequencing and inbox management platform.
Plusvibe manages your sequences and replies; Cladiant provisions the mailboxes behind them. Real Google Workspace, Microsoft 365, and Azure Entra accounts, authenticated end to end, connected straight into your Plusvibe workspace.
Dedicated Azure tenants and verified DNS mean the accounts you run in Plusvibe start on solid ground, one order and one invoice, with no manual inbox setup.
The handoff
How Cladiant hands off to Plusvibe
Cladiant connects mailboxes to Plusvibe with the username, password, API key, and workspace, so they land in your Plusvibe workspace ready to send.
Division of labor
Two layers, zero overlap
Plusvibe runs the campaign. Cladiant runs the infrastructure it sends from. Neither does the other's job, which is exactly why they fit together.
Cladiant handles
- Google Workspace, Microsoft 365, and Azure Entra mailboxes
- Domain purchase plus SPF, DKIM, and DMARC on every domain
- A dedicated Azure Entra tenant per domain
- Deliverability monitoring that pulls a bad inbox to warmup
- Month-to-month billing on one invoice
Plusvibe handles
- Sequencing and inbox management
- AI personalization and lead enrichment
- Placement testing (inbox vs spam)
- Reply handling and campaign analytics
Setup
From order to sending
- 01
Tell us your volume
Say how many emails a day you need to send. We size the mailboxes and domains so no single inbox or domain is overloaded.
- 02
We provision and authenticate
Real Google Workspace, Microsoft 365, and Azure Entra mailboxes, with SPF, DKIM, and DMARC written and verified on every domain before anything sends.
- 03
Connect to Plusvibe
We hand the accounts to Plusvibe using the credentials it expects, including a Microsoft OAuth link for Azure inboxes, so they land in your workspace ready to send.
- 04
Set safe limits and launch
Cap daily volume per mailbox, keep warmup running, and keep bounces low. Your campaigns run; we keep the infrastructure healthy underneath.
Sizing it
How many mailboxes you need
A safe cold-email cadence is 20 to 40 sends per mailbox per day across a few mailboxes per domain, with new mailboxes warmed up over two to four weeks and bounce rate kept low. A target of 1,000 sends a day works out to roughly 30 to 40 mailboxes across a dozen or so domains, and Plusvibe rotates across them for you.
What you get
Infrastructure built for the inbox
01
Three real providers
Google Workspace, Microsoft 365, and Azure Entra in one order, not a single-source SMTP relay.
02
Authenticated before sending
SPF, DKIM, and DMARC written and verified on every domain before a mailbox goes live.
03
Dedicated Azure tenants
Every Azure domain in its own tenant, so your reputation is never pooled with other senders.
Troubleshooting
When something goes wrong, who fixes it
Most cold-email problems are either a sequencer problem or an infrastructure problem. Here is how to tell them apart, and which layer owns the fix.
| Symptom | Likely cause | How it gets fixed |
|---|---|---|
| Emails landing in spam on seed tests | A DNS or authentication gap, or a blacklisted domain | Cladiant re-checks SPF, DKIM, DMARC and reputation, then remediates or replaces the domain |
| Reply rate declining over several weeks | Domain or inbox reputation wearing down | Cladiant rotates sending to rested mailboxes and warms the affected ones back up |
| Bounce rate climbing above 2 to 3 percent | List quality, not infrastructure | Pause and re-verify the list before sending more; suppress hard bounces in the sequencer |
| Good deliverability but low replies | Copy or targeting, not infrastructure | A/B test messaging in your sequencer; if a plain-text version also lands in spam, it points back to infrastructure |
| A sudden drop across many inboxes at once | A shared-reputation or tenant-level problem | Isolated Azure tenants contain the blast radius, so Cladiant investigates only the affected tenant |

Yes. Cladiant provisions across Google Workspace, Microsoft 365, and Azure Entra, so you can diversify providers behind Plusvibe instead of sending everything from one stack.
How many mailboxes do I need for Plusvibe?
Plan for 20 to 40 sends per mailbox per day across a few mailboxes per domain; for 1,000 sends a day that is roughly 30 to 40 mailboxes across a dozen domains. Our free volume calculator sizes it for you.
Do Cladiant mailboxes need warmup before Plusvibe campaigns?
Yes. New mailboxes should warm for two to four weeks at a 2-to-1 warmup-to-cold ratio. Cladiant mailboxes arrive authenticated and ready to warm, and Plusvibe placement testing confirms inbox placement before you scale.
Will Cladiant keep my Plusvibe sends out of spam?
Placement depends on the infrastructure Plusvibe sends from. Verified SPF, DKIM, and DMARC on dedicated Azure tenants give your Plusvibe campaigns a clean, isolated base, so one bad inbox does not pull the rest into spam.
