Mailivery integration

Warming up an email or a domain by yourself can be pretty time-consuming, especially with the preparation of the email's content and then sending your emails manually. With the Mailivery add-on in Woodpecker, the whole process can be automated.

The warm-up process will start with sending a few emails daily, and thanks to the Mailivery Email Ramp-up, which is turned on by default, it will be increased to a maximum of 50 emails daily. You can read more about Email Ramp-up here »

Warm-up emails will be sent Monday to Friday and will be matched to the time zone set in your account. The reply rate for those emails should be up to 55%.

Activating and adding warm-up

Our integration with Mailivery is available as a warm-up add-on in the Marketplace. You won’t be charged for activating the add-on, but every email account that is added to the warm-up process will cost $5/month.

After activating the add-on, you can start by adding email accounts to the warm-up process. To begin, go to your Accounts tab. You’ll see the option to add warm-up next to the email address connected to your Woodpecker account.

Choose the one you want to warm up, and after clicking on the link, you’ll be redirected to the page for adding and purchasing this option.

Besides First and Last Name, you’ll have to enter the App password (for Google accounts) or SMTP and IMAP Server data (for Sengrid and other providers). If you don’t know how to get the app password for Google, check our help article about it, or look for the tutorials from your provider.

Fill in the fields with the required information and click on the “Add warm-up” button. If all goes well, you will see a message that the addition was successful.

In case of an unsuccessful process, it might be two things: a payment problem or there was a problem with adding the warm-up overall. With the first one, check if the card connected is the correct one or if there are any funds available on it, and try adding the warm-up again.

With the second issue, contact our Support team, so we can check what went wrong in detail.

After the warm-up has been added, you can see the details in the Warm-up tab under the email account.

Next to the email account name, there will be three statuses for the warm-up: Active, Inactive, or Stopped.

Pausing and removing warm-up

The warm-up process can be stopped or paused by you at any time. Keep in mind that pausing can result in lower response rates because your email may be marked as spam.

Pausing your warm-up process won’t pause the payment for it – you’ll still be charged the same as having an active warm-up. Only after it is completely removed from the e-mail account will you not be charged.

Removing warm-up will result in credits being applied to your billing subscription.


For Google accounts, the warm-up process may have been stopped as an error for two reasons: either the email account is disconnected in Woodpecker, or there was a problem with connecting the warm-up to Mailivery.

The details of the account connected to the warm-up will show the specific reason for the error through a message in red, so you can either reconnect the email or fill in the App password again.

For Sengrid accounts, in case of an error, fill in the API Key, and IMAP password in the form again, and save changes to resume warm-up.

For Office accounts connected to warm-up, the solution to the error is reconnecting your account by clicking on the Office button below.

If any error message does not correspond to the above cases, please contact our Support Team.

Free warm-up

Depending on the contacted & stored prospects tier you have, a certain number of free warm-ups will be assigned to your account.

When activating the warm-up add-on, you'll see the exact number of free warm-up slots available for you. It can also be checked in the Accounts tab, at the top of the "Warm-up" column.

You can add mailboxes to the Warm-up process without charges – up to a number defined by your tier. Beyond that, every next mailbox will still cost $5.

If the tier of contacted and stored prospects is downgraded, the number of free warm-ups will also be reduced. This means that if you had 13 free warm-ups on your previous payment plan and used them all, and you only have 10 on a lower one, those 3 previously activated will be added to your bill.


Q.: How will I know which emails are from the warm-up process?

Every warm-up email you receive will have its code at the end of the message, and some part of it will be repeated in every email.

You can filter your emails with this input if you want them to be redirected to another folder in your inbox.

A "Mailivery" label/folder will automatically be created in your mailbox where all emails received from the warm-up will go.

Q.: How long should I keep the warm-up on?

We recommend having a warm-up enabled at all times so that your reputation remains good. However, you can turn it off after 8-15 weeks, but keep in mind that this way, you are not protected in case your email/domain reputation deteriorates.

Q.: Regarding the free warm-up, do I need to pay anything before adding it to my account?

We don't charge you when activating the warm-up add-on. You will be charged $5 per mailbox only when you add warm-up to more email accounts than the free warm-up slots you have.
