How We Processed 10K Contacts in 30 Minutes with Apollo to Smartlead Workflow

Overview

From campaign selection to outreach-ready contacts

The sales team used to move every prospect list through a long manual process between Apollo, Emailhippo, and Smartlead. I replaced those disconnected steps with one workflow that enriches contact data, improves email coverage, cleans personalization fields, and delivers verified contacts to the selected campaign.

Instead of managing files and fixing records one by one, the team now selects a campaign and lets the automation complete the remaining work.

The bottleneck

Manual list preparation consumed five hours per campaign

The team exported email lists from Apollo, uploaded them to Emailhippo for verification, corrected first names, and then imported the prepared file into Smartlead. Repeating those steps made campaign preparation slow and left plenty of room for inconsistent data.

Apollo also found email addresses for only around half of the selected contacts, and many of the addresses it returned were unverified. The team needed a way to recover more valid emails without adding even more manual research.

The solution

One automated enrichment and verification pipeline

I built a workflow that begins when the team selects a campaign. It extracts and enriches contacts from Apollo, verifies email addresses with Emailhippo, and routes failed contacts through Scrubby and Bettercontact to find more verified addresses.

The automation combines the results in Airtable and uses OpenAI to standardize first names and company names, identify salutations, and generate custom fields for each contact. Once processing is complete, it imports the verified contacts into the selected Smartlead campaign.

How it works

From Apollo search to Smartlead campaign

1. 01

   Select the campaign

   The team chooses the campaign to prepare, replacing the previous sequence of exports, uploads, and manual edits.

2. 02

   Extract and enrich contacts

   The automation retrieves the selected contacts from Apollo and uses Scrubby to enrich the available prospect data.

3. 03

   Verify email addresses

   Emailhippo verifies the initial addresses so only deliverable contacts move directly to preparation.

4. 04

   Recover failed contacts

   Contacts that fail verification are sent to Scrubby and Bettercontact to find additional verified email addresses.

5. 05

   Combine and clean the data

   The workflow merges the results in Airtable, removes unusable records, and gives the team one coordinated contact dataset.

6. 06

   Prepare personalized fields

   OpenAI standardizes first names and company names, identifies the appropriate salutation, and generates custom fields for each contact.

7. 07

   Launch in Smartlead

   When processing is complete, the automation imports the verified, cleaned contacts into the selected Smartlead campaign.

What I delivered

A connected contact-preparation workflow

• Campaign selection as the only manual starting step.
• Automated Apollo contact extraction and Scrubby enrichment.
• Primary email verification through Emailhippo.
• Recovery paths through Scrubby and Bettercontact for contacts that fail initial verification.
• Airtable-based consolidation and workflow tracking.
• OpenAI-assisted cleanup of first names and company names.
• Salutation identification and custom-field generation for every prepared contact.
• Automatic import of verified contacts into the selected Smartlead campaign.
