You might already know how Woodpecker sends emails using one mailbox, but what if you add a few more to take care of your campaign? This is what Woodpecker presents as Inbox Rotation – a mechanism that will help with your content deliverability, reduce the chances of exceeding the provider's limits, and thus relieve one mailbox from sending to all prospects.

When creating a campaign, click the “Add next email account” button to add another mailbox for sending. There is a limit of 100 email accounts that can be added to one campaign.

After that, carry on as you would normally do when creating a campaign. In the summary, you’ll see all of the addresses that will be used for sending out emails to your prospects.

It won’t be possible to add another mailbox unless the one before is not chosen from a list.

The way this process works is that each mailbox is assigned some prospects, and it all depends on the configuration of the mailbox – its limits, way of sending emails, use in other campaigns, and whether everything is properly connected.

If the mailboxes added to your campaign have different limits and different sending paces, the ones with bigger limits and smaller sending intervals would usually be given more prospects to cover in a campaign. If your goal is keeping it even, setting up those mailboxes with similar or the same configuration is recommended.

For campaigns that already exist and were created before September 21st, 2023 with only one mailbox – an example would be the campaign with 10 steps created and most of the prospects already on the 5th step. When you add another mailbox to such a campaign, a pop-up will appear informing you that this operation will result in your prospects receiving emails from different senders.

When removing a mailbox from a multiple mailbox campaign, prospects assigned to this email account will be placed on hold until they are assigned to another mailbox that matches their status. Keep in mind that follow-ups are always prioritized over opening emails, so it might take some time until those prospects start receiving emails. You will also see information about it when removing the mailbox from the campaign.

Tip: When writing an email copy and setting up sending from different mailboxes, be mindful of what you include in the message - if you want to introduce yourself, avoid writing your name, as you never know what address your prospects will receive the message from.

In the campaign edit mode, you can choose to include the email’s sender's signature when creating the email copy. Click on the “signature” icon in the edit bar at the bottom and choose between both options.

By using the sender’s signature, it will be added automatically from the sender’s email account, where it was set up (either at the moment of connecting the email to Woodpecker or separately). If you edit the signature in the mailbox settings, it will be automatically updated in the campaign.

If you choose not to include the sender's signature in the email, you can add it to the campaign step of your choice by simply typing or pasting it into the email editor.

With Inbox Rotation, the email signature will always be matched to the mailbox currently sending the message.

Q.: Will follow-up messages be sent from the same mailbox from the beginning?

Yes, unless that mailbox is removed from a Woodpecker account or a campaign. That is when the process will be restarted, and prospects may receive emails from a different sender.

Q.: Is there a limit on how many email accounts can be added to one campaign?

Yes, there's a limit of 100 email accounts in one campaign.

Q.: My campaign seems to have a problem with sending – Mailbox A sent 100 emails, and Mailbox B only 20. Why is that?

This scenario can mean that both mailboxes have very different sending limits and the sending is not evenly distributed, or Mailbox B has come across an issue at the beginning of a campaign, and those prospects left without a mailbox assigned have eventually been sent an email from Mailbox A.
