Need a tool for cold mailing? Get a tool built for cold mailing.

While Mailshake offers features for various online channels, Woodpecker was designed specifically for cold emailing. This focus helped us develop features that optimize your cold outreach efforts.

Woodpecker allows you to maximize open rates using A/B testing, sending follow-ups in the same thread and adding manual tasks (“call John”, “text Anna”, etc.) in between campaigns.

Optimized deliverability

Unlike Mailshake, Woodpecker has a number of features that maximize deliverability right from the start. Its built-in email verification and validation system prevents unnecessary bounces, so you don’t have to worry about your domain reputation.

Remember – cold emailing needs high deliverability and any tool that doesn’t focus on that will not deliver the results you expect.


Warming up emails is a very important process that helps you achieve top deliverability rates. Warm-up helps with this and is available for all Woodpecker users. It’s at least 5x cheaper than other warm-up tools.

Deliverability Monitor

Track your deliverability with Woodpecker and spot any issues before they happen so you can prevent them. No other cold email tool on the market allows you to do this.

With Mailshake, you have no idea if certain issues are preventing your mails from landing in recipient inboxes or not. Maybe they were delivered, maybe they weren’t…

Is that what you want to pay for?

Bounce Shield

With Woodpecker your deliverability is protected 24/7. Bounce Shield adjusts your sending frequency so you can be sure you won’t get blocked by your email provider for exceeding the sending limits.

You can rest easy knowing that Woodpecker is doing everything possible to make sure you connect with your prospects and start conversations that convert.

Optimizing campaigns

Woodpecker’s If-campaigns allow you to send diverse follow-ups triggered by your prospect’s behavior. With A/B tests, you may create up to 5 versions of an email and check which works best for your prospects.

Woodpecker performs the analytics for you by generating comprehensive performance reports after each campaign. With the data in place, you can easily optimize your efforts.


You can configure ‘Yes’ and ‘No’ paths for each campaign. Woodpecker will choose which one to follow depending on whether (or how many times) your prospect opened the email, replied to it or clicked on a link.

A/B tests

With the built-in A/B testing feature, you can experiment with your emails until you reach the best-performing copy and subject line. Create up to 5 different versions of your message (both opener and follow-ups) and put them to the test.


We prioritize easy integrations with the tools you already use.. You can integrate Woodpecker with all major CRMs, prospecting tools and other common sales software and easily analyze all your efforts.

Getting nice shiny toys for your marketing toolbox only makes sense if they all work together!
