Gmail mail merge questions

What does Flier do?

Flier is a web app for personalized email campaigns through your Gmail account. Import contacts from CSV, write a rich text message, preview each recipient's email, and send or schedule a campaign.

How do CSV fields become personalized emails?

CSV column names become template variables. For example, a name column can fill {{name}} in your message. Preview the results before sending to check missing values and formatting.

Does Flier bypass Gmail sending limits?

No. Emails are sent through Google's Gmail API and remain subject to your account's sending limits and anti-spam rules. Only email recipients who expect to hear from you.

Can I schedule campaigns and track results?

Flier supports scheduled delivery and campaign analytics, including open and click tracking. Open tracking depends on image loading and can be affected by privacy features in email clients.
