How to Set Up Twain with Smartlead

Learn how to connect the Twain and SmartLead native integration. Sync your AI-optimized sales copy and leads directly to your email campaigns with this step-by-step guide.

Connect Twain and SmartLead to export your outreach copy and lead lists directly into your sending sequences, without manual data entry.

1. Choose or create a campaign in SmartLead (optional)

You can export into an existing SmartLead campaign, or let Twain create a new one during export (see step 3). If you create it yourself, add a short placeholder text in the email body so SmartLead lets you save it. Twain's variables will replace it.

2. Connect the API

  • In Twain, open the campaign and click Export (or Export Leads), then choose SmartLead. If it isn't listed directly, click More first.

  • You will be prompted for your SmartLead API Key. You can find this in your SmartLead account settings.

  • Once entered, Twain will securely connect to your account and display your active SmartLead campaigns.

3. Choose the campaign and check the variables

  • Pick an existing campaign under Existing, or switch to New campaign and enter a name: Twain then creates the campaign in SmartLead with one email step per Twain step and the variables already inserted.

  • Check the variable names. Twain names them by channel, e.g. Email 1, Email 2, plus Subject 1 for the subject line.

  • Click Export Leads.

4. Verify and Preview

  • Open the campaign in SmartLead and check the Variables tab to verify the data arrived.

  • Use the Preview tool to see how a specific lead’s email will look.

  • Thread Tip: For follow-up steps (Email 2, 3, etc.), leave the subject line blank in SmartLead if you want the emails to appear in the same conversation thread.

💡Tips:

  • SmartLead needs an email address for every lead. Leads without one are skipped.

  • Turn on Skip existing leads to avoid exporting leads already in the campaign.
