FAQ

Can I use Gmail SMTP with BotSailor?
 Yes, you can use Gmail SMTP, but it’s recommended to use an App Password instead of your main Gmail password. However, Gmail is not ideal for bulk or marketing emails — use a professional SMTP provider like Zoho, Brevo, Mailgun, or your hosting SMTP for better results.

What should I do if the SMTP connection fails?
 Check your SMTP credentials carefully:

• Make sure the host and port are correct
• Ensure the username and password are valid
• Try toggling the SSL/TLS setting
• Some providers may require app-specific passwords (like Gmail or Zoho)

Do I need to verify my domain before using SMTP?
 While BotSailor doesn’t force domain verification, it’s highly recommended to verify your domain and configure SPF & DKIM records to improve deliverability and avoid spam issues.

Can I send bulk email campaigns through this SMTP integration?
 BotSailor’s SMTP integration is designed for automated 1-to-1 transactional emails via chatbot flows. For large-scale email campaigns, use proper email marketing tools or a bulk SMTP service that supports high-volume sending.

How can I use SMTP in a chatbot flow?
 Once your SMTP is configured:

• Go to your bot’s flow builder
• Add an “Email” action after collecting the user’s email address
• Select your SMTP provider and customize your email content

Is it secure to store my SMTP password inside BotSailor?
 Yes. BotSailor encrypts your SMTP credentials during storage to ensure data security and privacy.

Can I connect multiple SMTP accounts?
 Currently, each BotSailor account supports adding one active SMTP provider at a time. If you want to switch, simply remove the old one and add a new one.

Why are my emails going to spam?
 Common reasons include:

• Sending from a free email (e.g., Gmail, Yahoo)
• Missing SPF/DKIM records
• Using spam-triggering keywords or too many links/images
• Unverified domain or blacklisted IP

Will white-label resellers need to configure SMTP separately for their clients?
 This guide is only for BotSailor end users, not for white-label resellers. White-label SMTP integration might differ based on the reseller setup.

Is there any log to check if the email was sent successfully?
 Yes. You can check chatbot conversation history or error logs under the bot flow section to confirm whether the email was triggered and delivered properly.
