What Is Woodpecker?

How Woodpecker Works?

It sets up your domains and inboxes

Woodpecker provides domains and inboxes with SPF, DKIM, and DMARC pre-configured. Your emails are authenticated right from the start.

Then, it  checks your email addresses

Every address is checked automatically, so you only send valid emails and protect your sender's reputation.

Warms up your inboxes

Before big campaigns, inboxes are warmed up step by step to build a strong sender reputation.

Sends emails safely

Emails are rotated across inboxes, and sending limits are managed automatically to avoid spam issues.

Monitors deliverability

The deliverability monitor keeps track of performance and predicts potential issues, helping emails land in the inbox.

5 Best Woodpecker Alternatives for Strong Email Infrastructure 

Let's look at each tool in detail.

‍

1. Mailforge

Mailforge is a shared IP email infrastructure built for cold email teams that need fast, reliable setup without worrying about deliverability. 

Unlike Woodpecker, Mailforge focuses purely on infrastructure, giving you a backend optimized for scaling and inbox placement rather than managing campaigns inside the tool.

It uses shared IPs optimized for cold email, so your campaigns land in inboxes even at scale. 

You can create hundreds of domains and mailboxes in minutes, with automated DNS setup (SPF, DKIM, DMARC) handled for you.

Premium deliverability, SSL & Domain Masking, Inbox rotation, and multiple workspaces make it easy to scale your outreach safely.

• Compatible with Any Sending Software – Can be connected to any cold email sending tool using standard mailbox credentials.

• Mailbox Cost: Starts at $2.5 per mailbox per month, billed monthly. Minimum 10 mailbox slots required.
  
  
• Domain Cost: Around $14 per .com domain per year, billed once.

Mailforge Pros

“Setting up new domains and mailboxes is quick, and they stay portable—if we ever change tools, we can take everything with us without drama.”-Colin Graham, Trustpilot

• You can move or reuse domains easily instead of starting from zero every time.
  

Mailforge Cons

• You need another tool to send sequences and manage campaigns
  
  
• Shared IPs mean you don’t have full control over sender reputation, like with dedicated IPs
  
  
• Advanced outreach automation, A/B testing, or sequence-level analytics aren’t included; Mailforge focuses purely on infrastructure. 

‍

2. Infraforge

Infraforge is a private email infrastructure built for cold email teams that want full control over their domains, IPs, and deliverability. 

Unlike Woodpecker, Infraforge focuses purely on backend infrastructure, giving you dedicated servers and pre-warmed accounts for reliable sending from day one.

You can create thousands of domains and mailboxes in minutes, with automated DNS setup (SPF, DKIM, DMARC), Dedicated IPs, SSL & Domain Masking, multiple workspaces, and real-time deliverability monitoring, making it easy to scale safely and stay out of spam folders.

Key Features

• Automated DNS Setup – Every domain gets DMARC, SPF, and DKIM automatically configured
  
  
• Dedicated IPs – Each mailbox uses its own IP, keeping sender reputation clean and campaigns consistent.

Infraforge Pros 

• You are the only one using your sending IPs, so your reputation, inbox performance depend only on how you send.

• When deliverability drops, you can trace it back to a specific domain or IP instead of guessing.
  
  
• Infrastructure stays stable over time, which suits teams running the same offers for months.
  
  
• You can keep the same domains active for a long time, instead of rotating them every few weeks.
  
  
• Changes you make show clear cause-and-effect, making optimization easier.

Infraforge Cons 

• You still need a sending tool like Salesforge to send email sequences and manage campaigns.
  
  
• Dedicated IPs are optional add-ons, so scaling with private IPs can increase costs.
  
  
• Advanced sequence-level tracking, A/B testing, or analytics aren’t included.

Maildoso Cons

Mailscale Cons

• If deliverability drops, you must rely on Mailscale’s recovery process rather than fixing IPs or domains yourself.

5. Inframail
