Rick’s Review of Postmark Vs Greenarrow

Postmark and GreenArrow Engine are two email delivery software options that businesses can consider. Both have their own unique features and benefits that can help improve email deliverability and customer engagement.

Postmark is an email delivery service that focuses on providing high deliverability rates and reliable sending infrastructure. With Postmark, businesses can ensure that their emails reach the inbox and avoid being marked as spam. The service offers features such as bounce and spam reporting, DKIM and SPF authentication, and real-time analytics to track email delivery and engagement. Postmark also provides dedicated IP addresses to clients, which can further improve deliverability rates.

GreenArrow Engine, on the other hand, offers a flexible and secure SMTP and API email delivery solution. It is designed for businesses that require more control over their email sending process. GreenArrow Engine allows businesses to customize their email delivery settings, including IP addresses, delivery rules, and bounce handling. The software also provides robust reporting and analytics to track email performance and engagement.

Both Postmark and GreenArrow Engine offer comprehensive documentation and support to help businesses integrate and optimize their email delivery. They also provide detailed email logs and reporting, allowing businesses to troubleshoot and resolve any issues that may arise.

When comparing the two, businesses should consider their specific needs and priorities. Postmark may be more suitable for businesses that require a simple and reliable email delivery solution with high deliverability rates. On the other hand, GreenArrow Engine may be a better option for businesses that require more control and customization over their email delivery process.

While both options have their strengths, it is recommended that businesses thoroughly evaluate their requirements and conduct testing to determine which software will best meet their needs. Email deliverability is a critical aspect of any business’s email marketing strategy, and choosing the right email delivery software is crucial for success.

In conclusion, Postmark and GreenArrow Engine are two viable options for businesses seeking reliable and effective email delivery services. While Postmark focuses on high deliverability rates and a user-friendly interface, GreenArrow Engine offers more flexibility and control over the email delivery process. By carefully considering their unique needs and priorities, businesses can choose the option that best suits their requirements and helps them achieve their email marketing goals.

Beth’s Review of Postmark Vs Greenarrow

Postmark, an email delivery service, has recently introduced a new feature called the Retention Add-on. This add-on aims to help users ensure that their emails are delivered successfully and reach the intended recipients.

The Retention Add-on addresses the issue of email forwarding and its impact on email authentication. When an email is forwarded, the sender and header information may not get updated accordingly, resulting in authentication failures. In particular, two authentication methods, DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework), are affected by forwarding.

DKIM verifies the integrity of the message itself, ensuring that it hasn’t been altered during transit. While DKIM can withstand forwarding as long as certain mail headers and content are preserved, it becomes invalid if these elements are altered. On the other hand, SPF verifies the sending IPs and domains of the mail server, making it more susceptible to breaking as different mail servers process the message during forwarding. The forwarder may modify the Return-Path domain, causing SPF to become unaligned.

To address this issue, Postmark recommends having both DKIM and SPF set up, as DMARC (Domain-based Message Authentication, Reporting, and Conformance) only requires either DKIM or SPF to pass, not both. By having both authentication methods in place, if one breaks due to forwarding, the email can still pass DMARC. This is important for senders aiming to eventually move to a “reject” policy with DMARC, which ensures that only authorized mail is delivered.

Some email providers, such as Gmail and Outlook, are able to identify forwarded emails and can perform a “policy override” even if DMARC fails. This means that even if DMARC alignment is not achieved due to forwarding, the receiver can still deliver the email if it can validate that the message is genuine. The policy override is possible due to the use of another authentication standard called ARC (Authenticated Received Chain), which adds authentication results to the message headers when an email is forwarded.

While there isn’t a foolproof way to prevent alignment issues caused by forwarding, having a thorough understanding of the forwarding process and its impact on email authentication can help senders take necessary steps to minimize these issues. By implementing DKIM and SPF, senders can increase the chances of their emails passing authentication and reaching the intended recipients. Additionally, maintaining accurate records of all sending sources and ensuring they are fully authenticated before implementing a “reject” or “quarantine” DMARC policy can help avoid the potential blocking of legitimate mail.

Postmark’s Retention Add-on aims to assist users in identifying and addressing email authentication issues that may arise from forwarding, ultimately enhancing email deliverability and ensuring that important messages reach their intended destinations. This feature is particularly useful for senders who rely on email communication for important business transactions or customer interactions. With the Retention Add-on, users can mitigate the risks associated with forwarding, maintain DMARC compliance, and improve their overall email delivery performance.

Jennifer’s Review of Postmark Vs Greenarrow

In the forum post, a user named Sandeep Saxena asks if anyone has integrated MailWizz with Postal. Postal automatically sets a return path address sub-domain and inserts it into the email headers. However, all bounces go to Postal and don’t appear in MailWizz. Sandeep Saxena wants to know if there is a way to handle this so that bounces are processed by MailWizz.

Another user named twisted1919 suggests that Postal can post the bounces to a webhook URL, and MailWizz provides such a URL. In response, Sandeep Saxena thanks twisted1919 and asks for the webhook URL for DRH’s GreenArrow Engine.

Twisted1919 provides the webhook URL for GreenArrow’s engine. They also mention that a header needs to be added for it in the delivery server settings. The header name is X-GreenArrow-Click-Tracking-ID, and the header value is [CAMPAIGN_UID]|[SUBSCRIBER_UID].

Sandeep Saxena expresses his gratitude for the information. Another user named frm.mwz mentions that the available URLs for MailWizz can be found in the file \apps\frontend\controllers\DswhController.php.

In a later post, Sandeep Saxena mentions that under a live campaign, Postal is sending all data over a webhook, but they don’t see bounce statistics in the campaign, and the bounced addresses are not getting unsubscribed. They ask how they can check if MailWizz is receiving all the event notifications. Twisted1919 replies that MailWizz processes only specific events like ‘MessageDeliveryFailed’, ‘MessageDelayed’, ‘MessageHeld’, and ‘MessageBounced’. They assure Sandeep Saxena that they can pass all events, as MailWizz filters them out anyway.

GregKevey asks for the webhook URL for PostMark to track complaints and bounces. However, no one provides an answer to this question.

Laurentiu mentions that bounce processing for PostMark is not currently available in MailWizz, but it is on their roadmap for the future.

Overall, the forum post discusses the integration of MailWizz with Postal and GreenArrow. Users seek solutions for handling bounces and want to know about available webhook URLs for different email delivery services.
