A key decision is on the table: Woodpecker or Instantly?

Performance Showdown: 500-Lead Campaign Test Between Woodpecker and Instantly
Campaign Performance & Success Rates
Now, let’s talk about what really counts. We actually put them to the test by running real campaigns, 500 emails sent through each platform, to see how they perform in the real world.
We focused on two key metrics:
- Open Rates
- Reply Rates
The goal? Simple, to find out which tool truly drives engagement and sparks real conversations, not just lands your emails in inboxes.
Here’s what we discovered.
The results are clear. Instantly.ai outperformed Woodpecker in both open and reply rates, 44% vs 28.3% for opens, and 5.5% vs 0% for replies.
This suggests that Instantly’s approach to scale and automation gives it an edge when it comes to visibility and engagement.
Now that we’ve seen how both platforms perform in real campaigns, let’s take a closer look at their features and overall user experience to understand why these results differ.
Woodpecker Campaigns
Step 1: Setting the Stage – Campaign Creation
It all started inside Woodpecker’s campaign dashboard, where we launched a new test sequence: “SP–Testing Campaign Day 1.”
Using multiple sending accounts, we mirrored how real outbound teams distribute campaigns for higher deliverability. This setup allowed us to simulate a genuine outreach flow, spreading 500 leads evenly across accounts for a fair performance test.
Step 2: Email Path
Next came the sequence builder, the visual “Path” view, where you plan your outreach flow. We began by defining the send schedule and conditions, setting clear paths for “Yes” and “No” responses.
This gave us full control over when emails go out, what triggers follow-ups, and how prospects move through the funnel.
Using Woodpecker’s AI-assisted editor, we personalized the message dynamically with {{COMPANY}} and {{FIRST_NAME}} variables, keeping tone friendly yet direct.
Every detail was optimized for cold deliverability, from send-time windows (Mon–Fri, 8 AM–6 PM) to automatic signature management.
No campaign is complete without a follow-up, and Woodpecker makes that seamless.
We scheduled a second message to send 2 days after the initial email, but only if the recipient hadn’t replied.
This note carried a softer reminder, same thread, same tone, nudging the reader to take action while maintaining conversational continuity.
Step 4: Adding Prospects
Once the email sequence was ready, it was time to bring in the audience.
We imported 500 leads from a CSV file, testing Woodpecker’s intuitive upload and de-duplication system. With a single click, the platform matched contact fields and kept existing entries intact, clean data, no fuss.
Step 5: Preview
Before launching, we used the Preview mode to see exactly what each prospect would receive. It’s a small step but a crucial one, ensuring variables populate correctly and no embarrassing merge errors slip through.
Step 6: Launch and Live Stats
With everything locked in, we hit Play.
The dashboard instantly transitioned into live campaign view, tracking opens, clicks, replies, and opt-outs in real time. For transparency and analysis, results could be exported as CSVs for deeper performance comparison later.
Lead Finder
Woodpecker’s Lead Finder helps users discover and filter potential prospects.
You can search by location, company, job title, or industry, and the platform instantly returns a list of verified business contacts.
In this example, we filtered by U.S. state (Alabama) and found ready-to-use leads complete with company names, job titles, and email options. It’s a convenient way to fill your outreach pipeline directly within Woodpecker, no extra integrations or exports required.
Prospects
The Prospects section in Woodpecker shows all your contacts in one place.
You can filter leads by status, tags, company, or campaign, and quickly view key details like email, name, and LinkedIn URL. It also supports bulk actions, making it easy to update or add prospects directly to campaigns.
Deliverability
The Deliverability dashboard in Woodpecker provides a clear view of how campaigns are performing across all connected accounts.
It shows key metrics such as emails sent, delivered, viewed, replies, and bounces, helping users quickly identify potential sending issues.
You can filter results by campaign, account, timezone, and time period to get more specific insights. The summary helps track performance trends over time and maintain a healthy sender reputation.
Inbox
The Inbox section shows all campaign replies in one place.
Emails are grouped by status, such as Interested, Maybe Later, Not Interested, and Bounced.
You can also filter by campaign or email account to keep track of responses more easily.
Templates
The Templates section is where you can save and manage your email templates.
It allows you to create, edit, and reuse templates across different campaigns, saving time and keeping messaging consistent.
