Laposta email verification with BillionVerify
Laposta is a Dutch email marketing platform designed for creating, sending, and tracking newsletters and campaigns. Connecting it to BillionVerify lets you clean your subscriber lists before each send, cutting bounce rates and keeping your sender reputation healthy.
Why verify before the send
Sending campaigns to stale, invalid, or disposable addresses wastes budget and damages your domain reputation with ISPs. BillionVerify scrubs your Laposta lists for invalid syntax, dead mailboxes, role addresses, and catch-all domains so every campaign reaches a real inbox.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Laposta sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with Laposta
Ready-to-use workflows that verify emails before Laposta sends.
How it works
- 1
Install the BillionVerify community node in your n8n instance, or connect through Integrately with a single click.
- 2
In your workflow, pull subscriber data from Laposta using its API or a webhook trigger.
- 3
Pass each email address to the BillionVerify verification node, which checks deliverability, syntax, MX records, and disposable-address databases.
- 4
Filter results by verification status — keep 'valid', quarantine 'catch-all', and remove 'invalid' or 'disposable' addresses.
- 5
Update or segment your Laposta list based on the results, then proceed with a confident campaign send.
When to use this
Pre-campaign list hygiene
Before scheduling a newsletter, pipe your Laposta subscriber export through BillionVerify to remove undeliverable addresses. The result is a tighter, cleaner list that keeps your open rate meaningful and your bounce rate within safe limits.
New subscriber validation at sign-up
Trigger a BillionVerify check the moment someone subscribes via a Laposta form. Flag or reject invalid and disposable addresses on the spot so your list stays clean from day one rather than requiring periodic bulk scrubs.
FAQ
Does BillionVerify integrate directly with Laposta?
Yes — via the BillionVerify n8n community node, through Integrately's 1-click automation, or by calling the BillionVerify REST API from any webhook or script that can read your Laposta subscriber data.
What kinds of addresses does BillionVerify catch?
BillionVerify detects invalid syntax, non-existent mailboxes, disposable email providers, role-based addresses like info@ or support@, and risky catch-all domains that accept all mail but may not deliver.
How often should I verify my Laposta list?
A good rule of thumb is to verify any segment that has not been mailed in 90 days, and to validate new subscribers at the point of sign-up. Active, frequently mailed lists can be re-verified quarterly.
Will verification affect my existing Laposta automations?
No. Verification runs as a pre-processing step outside Laposta. You simply update or re-import the cleaned list before your automation or campaign fires, leaving your existing Laposta setup untouched.
