FAQ
What are transactional emails?
The term “transactional emails” stand for messages like account confirmations, password resets, purchase receipts, activity alerts, and other messages triggered by users’ actions.
How do I start sending transactional emails?
To start sending transactional emails, you first need to create an account in our transactional mail service, authenticate your sending domain (by adding a few technical records to your DNS, including SPF and DKIM records), and set up integration with your website, CRM, or any other application. To know more about the steps, and how each of the available integration options works, feel free to look through our guide, or connect with our 24/7 support team. We can also perform a demo for you if you wish.
What is the difference between transactional and regular emails?
Regular marketing email campaigns are mostly aimed at boosting sales and customer loyalty and are sent manually through email marketing platforms like Selzy. Transactional emails are sent automatically following a user’s action on the website or application, and have a more informative rather than promotional role. Usually, these emails are time-critical, and that’s why they require using another tool for email delivery to ensure they arrive fast and straight to the inbox.
Can I personalize transactional emails?
Yes, of course, you can. You can make your notifications more personalized by adding substitutions into your email templates for the fields you have in your database, such as name, location, order information, interests, etc.
What’s the fee for sending transactional emails?
New users of the service can send up to 6000 emails per month for free during the first 4 months. If you feel you need more, we can offer you fair pricing for different email volumes fitting any needs. For further details, visit the pricing plans page.
