QAFlow sends emails for password resets, new-user welcome, ticket notifications, and newsletter broadcasts. Without SMTP configured, emails use PHP mail() which often ends up in spam.

Recommended SMTP Providers

• Gmail (up to 500/day) — free, good for small sites
• Brevo / Sendinblue (300/day free) — best free tier
• Mailgun (5,000/month first 3 months) — high deliverability
• Amazon SES ($0.10 per 1,000) — cheapest at scale
• Hostinger Mail — if hosted on Hostinger, comes bundled
