Cladiant + Woodpecker
Mailboxes built for the inbox, connected straight into Woodpecker.
Woodpecker is a cold email and follow-up automation platform for agencies and B2B teams.
Woodpecker handles your sequencing and follow-ups; Cladiant handles the mailboxes and their reputation. We provision Google Workspace, Microsoft 365, and Azure Entra accounts, authenticate every domain, and connect them into Woodpecker.
With dedicated Azure tenants and verified SPF, DKIM, and DMARC, your Woodpecker sending starts on infrastructure built for the inbox, month to month, one invoice.
The handoff
How Cladiant hands off to Woodpecker
Cladiant connects mailboxes to Woodpecker with the account username and password, so they are ready to send from Woodpecker.
Division of labor
Two layers, zero overlap
Woodpecker 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
Woodpecker handles
- Cold email sequencing and follow-ups
- Condition-based campaign logic
- Reply detection and agency client management
- Deliverability reporting
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 Woodpecker
We hand the accounts to Woodpecker 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 Woodpecker 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 |
FAQ
Woodpecker + Cladiant, answered
Does Woodpecker include mailboxes?
No. Woodpecker handles your sequencing and follow-ups, but you connect your own mailboxes. Cladiant provisions real Google Workspace, Microsoft 365, and Azure Entra accounts and connects them into Woodpecker, so the sequencer and the infrastructure come from one order.
How do I connect Cladiant mailboxes to Woodpecker?
Cladiant connects mailboxes to Woodpecker with the account username and password, so they are ready to send from Woodpecker with no CSV import or manual per-inbox reconnect.
Can I use Google Workspace and Outlook mailboxes with Woodpecker?
Yes. Cladiant provisions across Google Workspace, Microsoft 365, and Azure Entra, so your Woodpecker campaigns can diversify across three real providers instead of relying on one stack.
How many mailboxes do I need for Woodpecker?
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. Use our free volume calculator to size it exactly.
Will Cladiant keep my Woodpecker sending out of spam?
Deliverability comes from the infrastructure Woodpecker sends through. Verified SPF, DKIM, and DMARC on dedicated Azure tenants give your Woodpecker campaigns a clean, isolated base, and monitoring pulls any affected inbox to warmup before it drags the rest down.
