Read below and let us save you time as we cover the best email warm-up tools in the market today, by the end of this guide you will be able to send emails like a pro to reach more inboxes than ever before!

Importance of Email Warm-Up Services

As you delve into the realm of cold emailing you will soon learn how essential a role email deliverability plays in your results.  It surely goes without saying that nothing is sadder than spending tons of hours on a campaign just for emails to end up in the Spam and Promotion inboxes of leads and potential customers.

While researching the best practices for cold emailing, you likely came across a strategy known as ‘inbox warm-up’, or ’email warm-up’ as many like to call it.  If you are unfamiliar with the term, it is the concept of gaining trust and credibility in the emailing industry.

Essentially, it is the process of hacking your way around spam and promotion filters, and in turn, enhancing your ability to reach the primary inboxes of leads or prospects.  Simply put, warming up an email raises your profit and bottom line, while preserving your sanity too!

With nearly ninety percent of received emails deemed spam, Email Service Providers (ESPs) took notice and put spam filters in place to prevent such emails from reaching primary email inboxes.

This spam filter works by detecting and preventing unwanted, unsolicited, and virus-filled emails from arriving in the main inbox of recipients.  These filters determine which emails are riskier based on factors like images and verbiage, the volume of emails sent from the address, and the email reputation of the sender.

Launched and managed by Mailshake, this service lets you warm a single account under the basic plan, which gives you fifty positive engagements from opens to replies to removal from spam boxes – actions that raise your credibility in the eyes of email service providers.  Let us take a look at some of the perks to be had with this email-warming service at your side.

Ease of Use

One perk of this service is they offer step-by-step guides that simplify and streamline the set-up process.

They also make it easy to connect a Gmail account so you can get up, running, and improving your email trust score in no time.  The downsides are you cannot filter inbox messages nor can you view prior warm-up results if your subscription ends.

Customization

• Ability to choose a reply rate.
• Can set the max number of daily emails.
• Able to increase volume as time goes on.
• Option to customize email body and subject lines.

Email Deliverability Results

During a test campaign, we saw our email deliverability climb from seventy-five to eighty-nine percent with this service.

Warm-Up Email Content

Sadly, email copy in their emails is poor and robotic, and with endings and greetings being obsolete, sender and recipient correspondences look far from being organic and genuine.

Analytics

• Ability to view views emails that were sent, opened, and replied to.
• User-friendly dashboard that shows the spam score (spam vs. inbox emails) for the four email providers they track, which are AOL, Gmail, Yahoo, and Yandex.
• Unable to view stats from a given time period.
• No email deliverability score is made available.

Customer Support

There is no live chat feature; sending an email is the only way to reach support.

This may be a turn-off for some as quick help will be unavailable if you need it.

Other Features

At the time of writing, no additional features are offered.

They do, however, have beta versions of an SPF, Spam, SMTP, and DMARC checker available but these may be inaccurate, and no official launch or release date of stable versions has been announced.

Price-to-Value Assessment

Overall, the service is worth using if you only care about warming up an email but when it comes to other features and customer support, they leave plenty to be desired! At $29 per month for a basic plan, we feel the price could be a bit lower, especially since live chat support is not a courtesy they extend to customers.

#8 Woodpecker

This email warm-up and sales automation solution brought futile results so we would suggest using another service as this Woodpecker actually lowered the email deliverability rate of our test campaign!

Ease of Use

• As the only upside worth noting, linking a Gmail account to the platform was a breeze.
• No option to filter inbox messages.
• The site is cluttered with tons of features and menu links that make finding the warm-up feature a tasking mission, this is the least user-friendly of all other platforms listed in this guide.

Other Features

• Prospect management.
• Automated email delivery.

Price-to-Value Assessment

At $49 monthly, the service is fairly priced if you find value in having a warm-up feature that comes with cold outreach automation bundled in but with customer support that seems to never reply, you may want to think twice about this service if you feel you will need technical help.
