Quick answers: Transactional emails and SMTP relay
-
What is a transactional email?
A transactional email is an automated message sent to a user in response to their online activity. These messages are personalized and typically contain important information relevant to the user’s action, including order confirmations, shipping notifications, password resets, purchase receipts, account updates, and personalized alerts.
-
What is the difference between a transactional email and a marketing email?
Transactional emails are automated messages sent to individuals following specific actions, like purchases, account changes or password reset request. They provide information needed to complete or confirm a transaction, are personalized, timely, and necessary for user interactions. Marketing emails, however, are designed for promotional purposes. They are sent in bulk to engage groups of users, increase brand awareness, or market services and products. The key difference lies in their intent and trigger: transactional emails are responses to user activities, whereas marketing emails are initiated by the company’s marketing strategies.
-
What are examples of transactional emails?
Transactional emails are automated messages sent to a user after specific interactions. Common types include:
- Order Confirmations: Acknowledge a purchase, detailing the transaction.
- Shipping Notifications: Provide updates on the delivery status of an order.
- Delivery Confirmations: Informs that the ordered item has been arrived at destination.
- Password Resets: Offer secure links for resetting account passwords.
- Account Alerts: Notify of changes or activity in a user’s account.
- Payment Invoices: Present invoices for services or products purchased.
- Subscription Renewals: Send reminders about ongoing service subscriptions.
- Support Tickets: Confirm a user’s request for help or feedback.
- Double-opt in: Verify that email belongs to the subscriber, preventing spam and improving deliverability.
-
What is an SMTP server?
A SMTP server is responsible for sending, storing, and receiving emails from one email provider to another. SMTP stands for Simple Mail Transfer Protocol, and it’s the standard technology for sending emails across the internet.
There are two types of SMTP servers:
- SMTP servers that manage day-to-day professional or private one-to-on email communication.
- Dedicated SMTP servers designed for handling high volume emails, such as bulk marketing messages or transactional emails.
-
What is the difference between a SMTP server and an Email server?
An SMTP server specifically handles the sending of emails by following the Simple Mail Transfer Protocol. An email server, however, plays a broader role, encompassing the SMTP functions as well as additional protocols like POP3 or IMAP, which are used for retrieving and storing emails. While SMTP is dedicated to sending emails, email servers manage the entire lifecycle of emails. This includes storing incoming mail, enabling users to access and organize their emails, and supporting the retrieval of emails across various devices.
Typically, mail servers incorporate an integrated SMTP server, which is suitable for regular person-to-person email communications. Beyond a certain volume of emails or for specific security reasons (such as maintaining domain integrity or limiting sender IP addresses) a dedicated SMTP server can be employed alongside the email server.
-
When should I use a SMTP relay server?
An SMTP relay server is recommended when you need to send large volumes of email securely, timely and reliably. It is particularly useful for businesses to ensure their emails reach the recipient’s inbox and not the spam folder. This service is crucial for maintaining a good reputation of your email domain, especially for important communications like transactional emails, marketing campaigns, and customer notifications. By using an SMTP relay, you reduce the risk of being blacklisted by ISPs and improve email deliverability. A SMTP server is your go-to solution, providing the infrastructure to handle both high volumes and the security protocols necessary for safe, effective email communication.
-
Why is it important to protect your domain when sending high transactional email volumes?
Protecting your domain when sending high transactional email volumes is crucial for maintaining your email reputation. If your domain is perceived as a spam source, it can lead to your emails being blocked or marked as spam (including your company’s day-to-day business emails), impacting the reach and effectiveness of your communications. High email volumes can trigger spam filters, so using SMTP relay services to protect your domain ensures clean traffic and prevents damage to your domain’s reputation. This protection is essential for reliable email delivery and maintaining your business’s professional image.
