Steve’s Review of Postageapp Vs Smtp.Com

PostageApp vs is a question that has been asked on Webmasters Stack Exchange. The user is wondering about the benefits of switching from their own SMTP server to an SMTP service. They mention that their server is set up with reverse DNS, SPF records, DomainKeys, DKIM, and SenderID, and they have not experienced any deliverability issues. They also mention that their SenderScore is reporting 99/100. So, they want to know why they should use an SMTP service instead of their own server.

One of the answers on the thread lists the key advantages of using a third-party mail sending solution. These include the fact that the onus of deliverability falls on the SMTP service provider, so the user doesn’t have to figure out deliverability issues on their own. The SMTP service provider also has the infrastructure to handle larger marketing initiatives and dedicated IPs to build the user’s reputation. Additionally, using an SMTP service allows the user to buy as necessary and close the account when they don’t need it anymore. The provider also offers reporting and metrics to track the success of the emails sent.

However, there are some disadvantages of using a third-party mail sending solution. Not all SMTP services support marketing campaigns or bulk emails, and it also costs money to use the service.

Another answer mentions that the costs of using a third-party provider are not that bad compared to building and maintaining your own solution. They suggest that if the user is only interested in the reporting aspect of using an SMTP service, they should check out PostageApp, which can be integrated into their existing SMTP infrastructure to provide better control and reporting.

Another response on the thread brings up some considerations for the user’s specific situation. They mention that sudden surges in email volume can trigger warnings from ISPs, so the user should consider throttling the campaign or sending it in stages to avoid this issue. They also note that SenderScore works like a credit rating and a sudden spike in email volume may go over the user’s threshold based on their past sending volumes. They recommend using email service providers (ESPs) that have IPs specifically used for bulk email and actively monitored for reputation management.

Overall, the answers on the thread highlight the benefits of using an SMTP service for handling large email volumes and managing deliverability issues. They also mention that while there are some costs associated with using a third-party provider, these costs are often worth it for the convenience and expertise provided.

SMTP (Simple Mail Transfer Protocol) is an email protocol used for sending email messages from one email account to another over the internet. It is one of the most common email protocols, along with POP and IMAP. SMTP is responsible for the transfer of email from a sender to a recipient.

An SMTP server is an application that provides a service to other applications within a network. It handles the sending, receiving, and relaying of email messages. SMTP servers work similarly to real-life post offices, processing and delivering emails to their final destinations.

To understand how SMTP works, it’s essential to understand the sending process and the commands used. When an email client sends a message, it establishes an SMTP connection to the server. The client uses commands like HELO or EHLO, MAIL FROM, RCPT TO, DATA, QUIT, and RSET to communicate with the server and transfer data.

SMTP error codes are used to indicate issues with email delivery. For example, a 4.X.X Persistent Transient Failure code signifies a temporary failure with the mail server, while a 5.X.X Permanent Error code indicates that the SMTP connection has dropped.

SMTP is different from other email protocols in that it is specifically used for sending email, while POP and IMAP are used for receiving email. SMTP is a “push” protocol, as it sends email from one server to another, while POP and IMAP are “pull” protocols that retrieve email from a user’s mail server.

When it comes to running an SMTP server, there are two options: running your own server or using a third-party email service. Running your own server allows for greater control over sending volume and email delivery monitoring, but it requires significant resources and technical knowledge. Using a third-party service, like Postmark, is less hassle and more cost-effective. It provides secure and reliable email delivery, expert deliverability, and technical support.

In conclusion, SMTP is a critical email protocol for sending messages. It works alongside POP and IMAP to facilitate email communication. Understanding SMTP and its features can help individuals and businesses make informed decisions about email delivery and choose the best SMTP service for their needs.

Dan’s Review of Postageapp Vs Smtp.Com

SMTP and API are two different methods of sending emails. SMTP stands for Simple Mail Transfer Protocol and is used to send emails across the internet. It works by transferring mail through a server and across a network to its destination. SMTP servers are specifically used for sending, receiving, and transferring email. On the other hand, API stands for Application Programming Interface and is used for more than just email. It is a software that enables multiple applications and systems to communicate through the Hypertext Transfer Protocol (HTTP). When it comes to email, API is used to automate the sending of transactional emails based on triggered actions.

SMTP has a few disadvantages, including slow performance for large volumes of email, changing deliverability of emails due to shared IP addresses, and the possible blockage of Port 25. However, there are also advantages to using SMTP, such as easy migration, easy setup, and simpler troubleshooting. On the other hand, using an email API has its own set of advantages and disadvantages. Some disadvantages include a steep learning curve, reliance on third-party intermediaries, and the need for coding knowledge to troubleshoot. However, the advantages of using an email API include reducing complexity in your app, removing server load, and getting analytics on your email sending.

When it comes to choosing between SMTP and API, there are a few things to consider. SMTP is recommended when you can’t add API functionality to your applications, or if you have an older system or sending method that already uses SMTP. SMTP can be used for both transactional and bulk email, but it tends to be slower than API. On the other hand, API is recommended in most cases where you can build it into your applications. API is faster and more flexible than SMTP, and it allows you to automate sending and tie messages to triggered actions.

Overall, understanding the differences between SMTP and API is important when it comes to integrating email into your apps or CRM tools. Choosing the right method depends on your specific needs and requirements. Whether you choose SMTP or API, both methods are essential for email development and deployment.

Title: Web API vs SMTP Relay: How Should You Send Your Email?

In the modern era of technology, sending emails has become an integral part of communication. Whether you are a business owner, marketer, or developer, finding the best method to send your email is crucial. Two primary methods of integrating with and sending email are SendGrid’s Web API and SMTP Relay. In this article, we will explore the differences between these two methods and help you decide which one is best for your needs.

Web API: The Efficient and Reliable Choice

SendGrid’s Web API is a method of sending email via HTTP. By using this method, your server sends a message to SendGrid, and receives a response indicating whether the message was accepted or if there was an error preventing its processing. This process is similar to putting a package in a mailbox and letting the post office review its information and deliver it for you.

One significant advantage of using the Web API is that it is faster than SMTP Relay. With SMTP Relay, there is more back and forth conversation required to deliver a message to the intended recipient. This can cause some latency, especially for customers outside of the United States who are further from the inbound data centers.

Additionally, the Web API allows you to add an extra layer of security to your program by utilizing API keys. These keys generate authentication credentials separate from your username and password, which significantly lowers the chance of someone using your account to send spam or phish.

SMTP Relay: The Tried and True Method

SMTP Relay, or Simple Mail Transfer Protocol, is a method of sending email that requires more back and forth conversation between SendGrid and its customers. This method is more like delivering a package yourself because it involves additional steps to complete the delivery process.

When a sender uses SMTP Relay to connect to SendGrid, separate pieces of information must be passed back and forth before the message can be processed and sent to the recipient ISP. This conversation includes checking the message, DNS, and authentication. Each step will return a response indicating whether something is right or wrong. A similar conversation takes place between SendGrid and the receiving ISP before the ISP can decide whether to deliver, block, or send the email to the spam folder.

SMTP Relay is a widely-used email standard and can be used to connect with existing applications like CRM systems or mail clients. It may be the preferred choice for those who are more comfortable with this method or have specific requirements for their email sending process.

Choosing the Right Method for You

While both methods have their pros and cons, there are a few reasons why SendGrid recommends using the Web API when possible. SMTP Relay creates multiple points of potential failure, meaning that there are more opportunities for something to go wrong during the conversation between the sender and SendGrid. The Web API is generally faster and more efficient, offering a smoother experience, especially for customers outside of the United States.

Ultimately, the choice between Web API and SMTP Relay depends on your specific needs and preferences. The Web API is a more modern and efficient method, while SMTP Relay is a tried and true email standard. Consider factors such as speed, security, and compatibility with existing systems when making your decision.


Sending email is an essential part of communication in today’s digital world. SendGrid offers two primary methods for integrating with and sending email: Web API and SMTP Relay. Each method has its advantages and considerations, and the choice depends on your specific needs and preferences. The Web API is faster, more efficient, and offers an added layer of security, while SMTP Relay is a widely-used standard that may be more compatible with existing systems. Choose the method that suits your requirements and send your emails with confidence.
