Bulk Email sends through your own SMTP or Amazon SES — so your only cost is your provider's, often a few dollars for tens of thousands of emails. Add several servers and rotate automatically.
Bulk Email guarantees your campaigns land in the inbox — never the spam folder, never blocked. Built-in DKIM/SPF/DMARC authentication, your own trusted sender reputation and smart warm-up keep every send delivered.
Backed by built-in deliverability technology and our 15-day money-back guarantee.
Amazon SES costs about $0.10 per 1,000 emails ($0.0001 each) with excellent deliverability. Bulk Email handles SMTP auth, rotation and DKIM for you.
Add one or many senders under the Sender Email tab. Bulk Email rotates between them, respects each one's daily limit, retries failures and auto-disables a sender if bounces spike — protecting your reputation.
Pick a provider and Bulk Email fills in the host and port. Use an app-password where required.
| Provider | SMTP host | Port | Security | Notes |
|---|---|---|---|---|
| Gmail / Workspace | smtp.gmail.com | 587 | TLS | Use an App Password (2FA on) |
| Outlook / Office 365 | smtp.office365.com | 587 | TLS | App Password if MFA enabled |
| Yahoo Mail | smtp.mail.yahoo.com | 465 | SSL | Generate an app password |
| AOL | smtp.aol.com | 465 | SSL | App password required |
| Zoho Mail | smtp.zoho.com | 587 | TLS | Enable IMAP/SMTP access |
| Amazon SES | email-smtp.<region>.amazonaws.com | 587 | TLS | Use SES SMTP credentials |
Settings shown for reference; providers occasionally change them.
Pick your email provider for the exact settings and how to get an app password where it's required.
Gmail needs an App Password — your normal password is rejected over SMTP.
