### [AhaSend](https://www.g2.com/products/ahasend/reviews)

AhaSend is a blazing fast pay as you go transactional email service. Transactional emails must reach the inbox quickly, and that is exactly where AhaSend excels. 💰 Fair and Transparent Pricing that Makes Sense Your first 1,000 emails each month are free. After that, plans start at $10 per month for 25,000 emails. If you go beyond your included volume, extra emails start at $0.50 per 1,000 with tiered discounts as you scale. No brackets and no hidden fees: you pay only for what you send. 🚀 Ultra Fast Transactional Email Delivery AhaSend consistently delivers transactional emails to Gmail in 0.5 to 2 seconds, to Yahoo in 2 to 4 seconds, and to Outlook in 3 to 5 seconds. Competitors often take double or triple that time in the best case, and frequently far more. If their shared IPs are also handling marketing traffic, delivery times can become unpredictable. AhaSend avoids that problem by focusing on speed and clean sending. 💥 Start Sending Now Get started immediately with the free 1,000 emails per month. No credit card required. 📊 Intuitive Dashboard with Metrics that Matter Search your email logs for up to 30 days, manage all your sending domains with deliverability tools, review delivery errors and suppression events, and monitor key performance metrics.

**Transactional email software** refers to software that sends emails in response to pre-established actions taken by recipients. These products send email notifications in response to users’ actions; some examples include a welcome email after creating a new social media account, an email receipt from an e-commerce transaction, or an email for a new newsletter subscription. Businesses use these tools for automating personalized emails as transactions occur. Teams use transactional email software to track metrics such as emails sent, received, opened, and bounced. Transactional email tools are useful to for customer retention, sales, marketing, and public relation teams. Transactional email software integrates with additional types of software, such as [CRM](https://www.g2.com/categories/crm-related), [email marketing](https://www.g2.com/categories/email-marketing), and[e-commerce products](https://www.g2.com/categories/e-commerce-platform), to maximize the benefits to your business.

To qualify for inclusion in the Transactional Email category, a product must:

- Provide automated email response tools
- Enable emails to be sent automatically as a result of action-based triggers
- Send customized or personalized emails
- Sync with business software such as e-commerce, social media, or other tools
- Provide administration tools to track emails sent and received, as well as their results
