Every morning, the agent checks HubSpot contacts added in the last day with NeverBounce and writes the result to each contact.

Option	How it works	Best for	Watch out for
Letaido AI agent	You describe the check. The agent pulls the addresses, runs NeverBounce, and writes results, tags or tasks back in 64 other apps.	Doing something with the result, like tagging Mailchimp members or asking a deal owner for a new contact.	65 apps, not thousands. NeverBounce can't start a job; a schedule or another app's event can.
NeverBounce native integrations	Connect an app such as HubSpot or Mailchimp in the NeverBounce dashboard to clean its lists.	Keeping one email tool's lists checked.	HubSpot Sync, for example, writes a result property. What happens next is up to you.
Zapier	Zaps that pass addresses between NeverBounce and other apps.	Apps with no native NeverBounce connection.	You build and fix each Zap.
NeverBounce API	Developers call the v4.2 API for single checks, bulk jobs and results.	Checking at sign-up in your own forms or product.	Code to write and keep running.

Frequently asked

How do I connect NeverBounce to Letaido? +

Add a card under Billing in NeverBounce, then copy the secret_ key from Apps, then Custom Integration. Paste it into Letaido's NeverBounce connector.

Does it use my NeverBounce credits? +

Yes, one per billable address. Duplicates and bad rows aren't billed. A sample bounce estimate spends none, and on request the agent shows the cost before a list check starts.

Can it verify contacts in HubSpot or Mailchimp? +

Yes. The agent reads the contacts, checks them in one NeverBounce bulk job, and writes the result to a HubSpot property or a Mailchimp tag.

Will it unsubscribe or delete bad addresses? +

Not in the jobs above. They write a result, a tag or a task, and you decide what to do.

How is this different from NeverBounce's HubSpot integration? +

NeverBounce's HubSpot integration writes a result code to a HubSpot property. Letaido's agent can also act on results across apps, like a Salesforce task for the deal owner.

What do I approve before it spends credits? +

Allow all read operations once per app; approve each kind of write once.
