FAQ:
❓ What is an SMTP?
SMTP stands for Simple Mail Transfer Protocol. It is the set of procedures, rules and principles to send emails/messages to an email server. Most development frameworks support SMTP. Therefore, there is no need to install additional libraries to get the SMTP protocol.
🚀 Which are the Best Free SMTP Servers?
Below are some of the best free SMTP servers:
❗ What is an SMTP Server?
An SMTP (Simple Mail Transfer Protocol) server is an application that is primarily used to send, receive or relay outgoing emails between the sender and the receiver. When a user sends an email, the SMTP server processes this email. After that, it decides the server on which the email will be sent and relays it to the server. Then, the server provider of the receiver downloads this email and puts it in the recipient’s mailbox.
⚡ Why do you need an SMTP Service?
Here are the reasons of using SMTP service:
- Helps to send more Emails per hour
- SMTP servers help to save money by ensuring maximum email delivery
- Helps you to keep your email list private and secure
- Allows users to add custom features to their Email campaign
- Supports Bulk Email Sending
🚀 What is the Can-Spam Act?
The CAN-SPAM Act is a cyber law that sets the rules for commercial Email, that gives recipients the right to stop sending messages and emailing them, and spells out tough penalties for violations.
However, it does not only apply to bulk Email. It also includes commercial messages, which the law defines as “any email message”. The primary purpose is the commercial advertisement or promotion of a commercial product or service.
It also includes Email, which promotes content on commercial websites. The law makes no exception for B2B Emails. For example, a message to former customers announcing new service or product lines must comply with the law.
🏅 What is Send Time Optimization (STO)?
Send Time Optimization (STO) is a method that uses data science to determine when your contacts are likely to engage and send your email marketing message at that time.
Here are important things that you should know before starting this process:
- Based on your plan, you may not have access to Send Time Optimization. First, you should know what features are included in each plan.
- You can use Send Time Optimization for plain-text, A/B testing, and multivariate email types. However, this feature is not available in automated emails.
- You should use this method only when five hours left in a day in the time zone set for the account.
👉 How to select an SMTP Provider?
You should look at the following parameters while selecting an SMTP service provider:
- Deliverability: A robust server infrastructure and proven delivery rate helps you to ensure that all your transactional and commercial messages reach to the recipient.
- Delivery speed: Delivery speed is the number of emails sent per unit of time (minute/ hours). It is important to have a high delivery speed if your email list is large.
- Dedicated IP: It is important that the SMTP provider assigns you a dedicated IP so that any spamming activity done on any other shared IP does not affect your deliverability.
- Bounce back handling: A high number of consistent bounce back can hurt your email marketing campaign. To reduce this, your site should have a good sign-up form, regular updated information, and most important, regularly schedule your emails.
- Feedback loops: A Feedback Loop (FBL) is a service offered by some ISPs that tracks the activity when a subscriber hits the spam or junk button in their inbox and notifies to senders. It is provided to aid senders in keeping the clean contact list.
- Tracking: You should also make sure that your email service provides has a consolidated dashboard with all the statistics you need. For example: clicks, open rates, bounces, unsubscribes, and an option for social sharing.
- Customization: It should provide the power if you want to change feature of a template so you can make it your own.
- Define your budget: The last but probably most vital thing you need to look before selecting the email service provider is budget. While you have an option for selecting low, medium, and enterprise-level providers, selecting the right one for your needs helps you to lower the cost and ensures high Return On Investment (ROI) while still delivering the functionality you need.
⚡ What is email deliverability, and why is it important?
Email deliverability is the ability to deliver emails to subscribers’ inboxes. It is important because some email marketers gauge the likelihood of their email campaigns reaching their subscribers’ inboxes.
For example, if you send 100 emails, and 50 emails didn’t reach to subscribers due to IP reputation, catch-all, stale emails, high bounces, etc. reasons, your open rate is already down by 50%.
Email deliverability is determined by the email delivery parameters like ISPs, throttling, bounces, spam issues and bulking.
❗ What are SPF, DKIM, and DMARC records?
- SPF (Sender Policy Framework) is a protocol for validating email, which is designed to find and block email spoofing.
- DKIM (Domain Keys Identified Mail) is a method for authenticating email. It enables receivers to know that the email which was sent to them is authorized by the domain author.
- DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a protocol for email authentication. It is specifically designed to give email owners the ability to safeguard their domain from unauthorized use.
It is also important to set SPF, DKIM, and DMARC for your email accounts to avoid spoofing and spam.
