Managing multiple email addresses within Marketo can be tricky, but it's a common challenge in many marketing automation strategies. Often, prospects or customers have alternate email addresses for different purposes (e.g., work and personal emails), and managing them accurately is essential to creating meaningful and personalized marketing experiences.
However, challenges arise when replacing the Primary Email Address with alternate emails, leading to record invalidation and unreliable reporting. To address these issues, we should develop a scalable solution to track, validate, and manage invalid email records efficiently.
Common Challenges
- Invalid Lead Records: Marketo marks the entire lead record as invalid if any email hard bounces, making it difficult to pinpoint the exact cause.
- Lack of Email Tracking: No visibility into which specific email field caused the invalidation.
- Compromised Email Campaigns: Marketo’s standard email field is used when executing targeted campaigns and is often replaced with alternate emails. If any of these emails are invalid or experience a hard bounce, Marketo flags the entire record as invalid, leading to misleading performance data.
- Impact on Deliverability: High bounce rates degrade the sender's reputation, negatively affecting the overall email success and database hygiene.
- Resource Waste: Manual troubleshooting is time-consuming and inefficient, diverting valuable resources from strategic marketing initiatives.
Effective Tactics
1. Bounce Management & Enrichment
- Understand Bounce categories and create reports for monitoring leads falling under those categories.
- Monitor bounce trends and track invalidation reasons.
- Score each hard bounce that happens. Using smart campaigns to increment hard bounces by +1.
- Maintain an Active Bounce List to manage scored high-risk leads.
- Create a strategy to Enrich blank Main Email Addresses with alternate valid emails.
2. Automated Email Validation After Enrichment
- Using email validation tools can improve deliverability and reduce bounces. For example:
👉 ZeroBounce – Detects spam traps, abuse emails, and catch-all addresses, with real-time validation API.
👉 NeverBounce – Offers real-time verification, bulk list cleaning, and integration with Marketo.
👉 Kickbox – Flags disposable and role-based emails and integrates easily with Marketo.
and more...
- Prioritize email fields and design a validation workflow (e.g., Primary Email → Work Email → Personal Email).
- Automation Flow:
- Align validation triggers based on new lead creation or email enrichment or email updates.
- Assign email invalid status (Valid, Invalid, Spam, Unknown, etc.).
- If the Primary Email is invalid, replace it with an enriched valid email or flag it and add it to a Suppression List for filtering.
3. Testing & Go-Live
- Prepare a thorough checklist for implementation.
- Conduct sandbox testing for each email category.
- Phase production rollout with scheduled batch validation.
- Integrate ongoing validation through the Active Bounce List.
