Building an effective cold email and outreach workflow doesn’t have to be complicated or require advanced AI personalization. For most B2B campaigns, a robust and streamlined process can deliver excellent appointment rates and clean, actionable lead data. In this article, we’ll break down the essential steps of a basic, actionable workflow in Clay – from lead import to validated, ready-to-contact prospects. If you’re aiming to increase your cold outreach results while minimizing manual work, mastering this core workflow is a must.

Why a Simple Clay Workflow Works for Most B2B Campaigns
The primary topic of this guide revolves around creating a cold email workflow in Clay that’s both simple and effective. While advanced enrichment and personalization techniques can be valuable for high-touch campaigns, the bulk of B2B lead generation needs are satisfied with reliable, automated cleansing, enrichment, and list preparation. This is especially true when working with databases like Apollo and integrating external enrichment and verification tools.
Our experience generating thousands of sales appointments for B2B clients proves that a foundational workflow – without unnecessary complexity – is sufficient for at least 90% of campaigns.
- Fast, repeatable setup reduces friction for every campaign
- Essential lead data cleaning and enrichment ensures contact quality
- Automations eliminate manual errors and speed up delivery
- Works natively with Apollo, LinkedIn, and major email verification tools
Starting Your Clay Table: The Critical Data Columns
The foundation of your workflow starts with the initial lead import. Typically, you’ll import your prospects from a source like Apollo, ensuring you capture both company and contact fields. A best-practice starting table includes:
- Company name
- First name
- Last name
- Full name (created with a simple Clay formula: First Name + Last Name)
- Website
- LinkedIn URL
- Job title
- Email (if available)
If you lack certain fields (such as emails), Clay’s enrichment tools will help fill those gaps later. Creating formulas, for example to merge first and last names, is user-friendly in Clay – you simply insert a new column and use the AI formula builder to concatenate fields. This setup streamlines later enrichment and personalization.
Cleaning Company Domains for Consistent Matching
Consistent domain cleaning is vital for later deduplication and enrichment. Clay AI formulas easily remove prefixes like ‘https’, ‘www’, slashes, and colons from your website URLs. This step standardizes domains for more accurate do-not-contact (DNC) checks and enrichment lookups.
Implementing Do-Not-Contact (DNC) and Domain Filtering
To protect your deliverability and avoid contacting current clients, opt-outs, or sensitive accounts, set up an automated lookup against a “DNC” (do not contact) table.
How the DNC Lookup Works in Clay
Using the Lookup Multiple Rows in Other Table feature, you can automatically compare your prospect list’s cleaned domain column against a separate table listing all companies or emails to avoid. If a match is found, the workflow excludes that row from all subsequent steps. This crucial step reduces the risk of domain or mailbox complaints, especially as you scale.
It’s also possible to reference external sources like HubSpot or Salesforce for DNC checks. However, checking within Clay’s own tables is often faster and less resource-intensive, especially for bulk operations. For each validation or enrichment step that follows, always add a condition: skip if prospect appears in DNC table.
MX Provider Checks: Filtering by Mailbox Delivery Risks
Deliverability is the cornerstone of successful cold email campaigns. Certain providers, like Microsoft 365, are known to have stricter spam filters or delivery issues for cold outreach. Integrating a free MX provider check into your Clay workflow helps you:
- Identify prospects using mailbox providers with high bounce or low engagement rates
- Exclude or segment these domains before further enrichment or send-out
Tools like the Lid Magic MX Checker offer a free HTTP API that’s easy to connect in Clay. Simply create an HTTP API column, point it to the MX check endpoint, and use the result (“Microsoft 365” or otherwise) as another run-condition for downstream steps.
Automating Step Logic: Skip, Run, or Pause Based on Previous Results
A functional workflow tracks results of every enrichment or validation step and triggers subsequent actions only if certain run conditions are met. For example:
- Skip email validation/enrichment if prospect is on the DNC list
- Skip validation if MX provider is Microsoft 365
This level of granular logic ensures no wasted API credits and higher process efficiency.
Email Verification and Enrichment: Ensuring Contact Quality
Not every import will provide you with a verified or even existing email address. High-quality workflows leverage multiple layers of enrichment and verification to maximize valid leads and minimize bounce rates.
Primary Email Verification Workflow
When an email address is already present, the verification process typically follows this order:
- Use an email validation API (such as Debounce) to check if the address is safe to send, catch-all, risky, or invalid
- If the mailbox is marked invalid or unknown, move to alternate enrichment sources
If no email is present, trigger a real-time enrichment step using platforms like Prospero, which often provide strong coverage for business emails. Only run enrichment steps for rows where no DNC record is present and the mailbox provider is not flagged for avoidance.
Handling Catch-All and Risky Emails
Emails marked as “catch-all” or “risky” require additional verification to reduce the chance of high bounce rates. One effective tactic is:
- Merge catch-all or risky emails into a designated “email for verification” column
- Use a secondary validation tool (such as Unreach.so) via an HTTP API column to perform a second layer check
If an email passes the secondary test as valid, you can safely proceed to send. The use of multiple verification tools dramatically reduces the risk of poor sender reputation or campaign suspension.
Master Email Column: Prioritizing the Safest Contacts
To streamline export and ensure only the best leads reach your campaigns, use a “master email” column. This column merges all validated and enriched results in a specific priority order:
- First, accept emails marked ‘Safe to Send’ by your main validator (e.g., Debounce)
- If none, use Prospero’s validated emails
- Finally, use double-validated emails from Unreach.so or similar
This approach ensures that every lead going into your outreach tools (like Instantly, Smartlead, or others) has passed at least one – and often two – validation checks.
Cleaning Company Names for Personalization
Small details make a big difference in personalization. Company names exported from databases are often cluttered with suffixes like LLC, Inc., or descriptive phrases. Before using these values in your email copy, you should clean them using Clay’s AI formula columns:
- Remove legal endings (LLC, Ltd, Inc.)
- Strip off generic descriptors (e.g., “Smart Agriculture” to “Agrology”)
- Keep names concise and copy-ready for message templates
Only run this cleaning step if the master email is not empty to save on credits and avoid unnecessary processing.
Adding Qualified Leads Directly to Campaigns
With clean, validated data, the final step is automating the addition of leads to your outreach platform of choice. This can be done through direct integration or export, ensuring only those who meet every condition (safe email, clean company name) are imported. Regularly test with small samples before running the workflow on larger batches to verify setup accuracy and avoid bulk errors.
Practical Tips for Onboarding, Scaling, and Troubleshooting
Launching your first outreach campaign in Clay with this workflow is simple. But for ongoing success, keep in mind:
- Always start with a small test run: verify that each step executes as intended and no records are mis-filtered or lost
- Document and update your DNC table: regularly add new client domains, unsubscribers, or complaint addresses
- Monitor deliverability results: update your MX filter list based on actual bounce data over time
- Experiment with additional enrichment tools for waterfall processing if base coverage drops
- Review “catch-all” hit rates and adjust your workflow to maximize valid sends
This reliable framework enables you to scale outreach, confidently knowing your list is clean, compliant, and optimized for engagement.
