Facebook lead ads generate hundreds of qualified prospects each month, but without a system to route them, they sit idle in your account collecting dust. Mailvio makes it simple to build email lists, segment subscribers, and automate campaigns—but only if your leads actually reach it. With LeadSync, every Facebook lead automatically syncs to Mailvio in real time, ready for email nurturing and conversion.
Log in to your Mailvio account and navigate to your account settings. Click on Integrations (or API settings, depending on your Mailvio plan). Copy your API key—you’ll need this to authenticate LeadSync. Keep this key private; treat it like a password.
Log in to your LeadSync account and go to Connections. Click Add New Connection and select Mailvio from the list. Paste your API key into the form and click Authenticate. LeadSync will verify the key and confirm your Mailvio account is connected.
Once authenticated, LeadSync will display all available subscriber groups in your Mailvio account. Choose the group where you want Facebook leads to be added. You can create a dedicated group for lead ads (e.g., “Facebook Leads Q1 2026”) or use an existing segment. This selection applies to all leads synced through this connection.
In LeadSync, go to Lead Sources and select Facebook Ads. Click Authorize to connect your Facebook account (you’ll be redirected to Facebook to grant permissions). Once authorized, select the specific lead form you want to sync. You can set up multiple Facebook forms to different Mailvio groups if needed.
Now the critical part: field mapping. LeadSync will show all fields from your Facebook lead form alongside fields in Mailvio. Email is required and must be mapped. Map first name, last name, phone, and any custom fields you’ve defined in Mailvio. If a field isn’t available in Facebook, leave it unmapped—Mailvio will accept the lead without it. Save your mapping when complete.
Before going live, submit a test lead through your Facebook ad form. LeadSync should sync the test lead to Mailvio within 10 seconds. Log in to Mailvio and verify the lead appears in your chosen group with all fields correctly mapped. If the test passes, you’re ready to start syncing real leads at scale.
Once your Facebook-to-Mailvio sync is running, you have several customization options. Create multiple connections if you run different ad campaigns targeting different audiences—each campaign can sync to a different Mailvio group. Use custom fields to capture additional data from your Facebook form (e.g., product interest, budget, company size). In Mailvio, set up automation workflows triggered by new subscribers from your lead group—send a welcome email, nurture sequence, or route to sales based on field values.
LeadSync also supports field transformations, so you can standardize data before it reaches Mailvio. For example, if Facebook captures “YES” or “NO” for a custom field but Mailvio expects “true” or “false”, LeadSync can handle the conversion.
Facebook leads are valuable on their own, but their true power emerges when you route them to multiple channels simultaneously. Use LeadSync to send every Facebook lead to Mailvio AND notify your team in real time.
With LeadSync, one Facebook lead can trigger multiple actions—to Mailvio, your team, and your internal systems—without manual intervention or third-party tools like Zapier.
Looking for a different destination for your Facebook leads? These integration guides walk you through setup step by step:
Most leads appear in Mailvio within 5-15 seconds of submission. This speed is achieved because LeadSync pulls from Facebook’s webhook system, not periodic polling. Your subscribers are ready for email campaigns immediately.
LeadSync checks Mailvio for duplicate email addresses by default. If the same email appears twice, the second submission updates the existing subscriber with any new field data. You won’t have duplicate subscribers clogging your list.
Yes. Any custom field you’ve created in your Facebook lead form can be mapped to a custom field in Mailvio during setup. LeadSync supports an unlimited number of custom fields, so capture whatever data your sales process requires.
No. LeadSync charges a flat monthly rate, not per lead. Sync 100 leads or 10,000 leads—your subscription cost stays the same. This pricing model makes scaling your ad spend risk-free from a software perspective.
Yes. Create separate Facebook-to-Mailvio connections in LeadSync for different campaigns or audience segments. Route leads from Campaign A to Group A and leads from Campaign B to Group B. Each connection has its own field mapping and subscriber group selection.
Both work, but LeadSync is simpler and cheaper. Zapier charges per task and per lead, adding up quickly at scale. LeadSync is a flat rate with no per-lead fees, built specifically for lead synchronization, and includes features like duplicate detection and field transformation built in. No Zapier configuration required—just map fields and go.
Absolutely. LeadSync offers a free 14-day trial with no credit card required. Set up your Facebook-to-Mailvio sync, test with real leads, and experience the speed and reliability yourself. No strings attached.
Mailvio’s API is available on most plans. If you’re on an older or custom plan without API access, contact Mailvio support to upgrade. The cost is minimal compared to the time you’ll save automating lead capture and follow-up.
