Connect EmailOctopus

When you create a campaign in OptinMonster that you intend to collect leads with, you’ll want to integrate with one or more services to send those leads to.

To send leads to EmailOctopus, follow these steps:

  1. Before you start, you’ll need an EmailOctopus API Key. You can generate and copy an API Key from your EmailOctopus account following this guide.
  2. Navigate to the Integrations view in the campaign builder, search for and select EmailOctopus.
    Select EmailOctopus to integrate with OptinMonster.
  3. Enter an EmailOctopus Account Name (*internal use only) and your EmailOctopus API Key in the appropriate fields, then select the Connect to EmailOctopus button.
    Connect EmailOctopus with OptinMonster.
    *The EmailOctopus Account Name can be anything that helps you identify the specific integration within OptinMonster. It’s possible to add more than one EmailOctopus integration to your account and this is an easy way to differentiate between them when assigning integrations to individual campaigns.
  4. Required: Once the EmailOctopus integration has been connected select the EmailOctopus Campaign you wish to send leads to from the Email Provider Lists field.
    Select a List to add leads to in EmailOctopus.

Email Automations

To send emails automatically to new leads you’ll want to configure email automations within your EmailOctopus account.

The following guides from EmailOctopus may be helpful to get started:


We strongly recommend you test the optin form before publishing your campaign to ensure it is working as you expect.

Before you begin, please be aware of the following details when testing EmailOctopus integrations:

  • Previously submitted or already subscribed leads may be treated differently by EmailOctopus than new leads. For this reason, we recommend using a completely unique email address each time you test submit your campaign’s form. You can use a free tool like or learn how to create unlimited unique email addresses from a single Gmail account.
  • If the lead is captured in EmailOctopus but you do not receive any automated emails it indicates the integration from OptinMonster to EmailOctopus is correct, and the issue is with the automated email configuration. EmailOctopus controls email automation exclusively. If you require assistance in troubleshooting email automations we recommend reaching out to EmailOctopus support directly.

Get started testing with the Live Site Inspector tool.
