We are proud to announce the release of Gravity SMTP 2.3. This update introduces a much-requested feature – email routing – giving you the ability to send emails through various integrations based on conditional rules.
In addition to email routing, you’ll find smarter handling of suppression with new filtered states, message flow settings for the Postmark integration, and support for custom attachment file names in six other integrations.
Gravity SMTP is available for free to anyone with an active Gravity Forms Elite, Nonprofit, or Developer license. If you hold one of these licenses, simply go to your Gravity Forms Account section to download Gravity SMTP today!
Let’s take a closer look at what’s new in Gravity SMTP 2.3…
New conditional email routing feature
Up until now, Gravity SMTP could send all your WordPress emails through one main integration, with optional backup. This works fine on most sites, but many of you told us that you want more control over which services send which emails.
With email routing, you have it. You can now create conditional rules that determine which integration handles each message.
Some examples of things that make this possible:
- Send your Gravity Forms notifications via Brevo, while your WooCommerce order emails are sent via Amazon SES.
- Route email to specific recipient domains through Google Workspace, while other domains use your default integration.
- Send emails with “Invoice” or “Receipt” in the subject line via Postmark, which is created specifically for this type of transactional email.
How email routing works
Setting up email routing means creating one or more routes. Each route matches an email with a condition, such as a subject line, sender address, or source, and sends it through the integration you choose.
To save you time creating a general configuration from scratch, email routing comes with a series of presets that you can add and customize:
- Admin Notice separate your site’s system email from the email users see.
- Handle Large Emails routes messages over 500 KB, or with attachments over 1000 KB, to certain integrations.
- High Volume Notifications route sends more than 5 emails at once to a custom integration.
- Gravity Form Submission with Files route in the form of a notification email that includes a file attachment.
If WooCommerce is active on your site, you will also see the WooCommerce Priority Order preset. All presets are fully editable, so treat this as a starting point, not a fixed template.
Build and customize routes
Whether you edit a preset or create a route from scratch, conditions are flexible. In addition to exact matches, they can check whether a value contains, starts with, or ends with text of your choice, with regex support for more complex patterns.
Routes are checked sequentially from top to bottom, and the first suitable route is used. If none match, the email will be sent via your default integration, and if the integration selected by the route fails to send, Gravity SMTP automatically tries your backup before logging the failure in the Email Log.
One thing to note: You’ll find the new settings below Settings > Email Routing. However, email routing requires at least two active integrations, so the setup screen only appears after you have configured two or more.
Test before you go live
Routing rules are what you want to ensure before the original email is sent. The new test email routing feature lets you simulate emails based on your current rules and see exactly which rules and integrations will handle them, evaluated in the same order as live sends.
For more information, see the Email Routing documentation.
Smarter bullying handling
Gravity SMTP 2.3 also improves how suppression lists work when an email has many recipients.
Previously, suppression only checked the recipient of the first email. Now every address in the to, cc, and bcc fields is checked, and any hidden addresses are removed before sending.
When this happens, the email will be marked with a new Filtered status in the log, so you can see at a glance that an email was sent with one or more recipients removed.
Additional updates
Additionally, Gravity SMTP 2.3 includes the following updates:
- Postmark: Message Flow Settings – Postmark users can now define Message Flows when sending emails, making it easier to separate transactional and broadcast sends on the Postmark side.
- Custom attachment file name – Support for custom filenames in attachments now extends to Custom SMTP, PHP Mail, Amazon SES, Google, Microsoft, and Zoho integrations.
- Developer filter update – The
gravitysmtp_connector_for_sendingfilters now accept the email source as a third parameter, so if you select the connector in the code, you can now route based on the email origin.

PakarPBN
A Private Blog Network (PBN) is a collection of websites that are controlled by a single individual or organization and used primarily to build backlinks to a “money site” in order to influence its ranking in search engines such as Google. The core idea behind a PBN is based on the importance of backlinks in Google’s ranking algorithm. Since Google views backlinks as signals of authority and trust, some website owners attempt to artificially create these signals through a controlled network of sites.
In a typical PBN setup, the owner acquires expired or aged domains that already have existing authority, backlinks, and history. These domains are rebuilt with new content and hosted separately, often using different IP addresses, hosting providers, themes, and ownership details to make them appear unrelated. Within the content published on these sites, links are strategically placed that point to the main website the owner wants to rank higher. By doing this, the owner attempts to pass link equity (also known as “link juice”) from the PBN sites to the target website.
The purpose of a PBN is to give the impression that the target website is naturally earning links from multiple independent sources. If done effectively, this can temporarily improve keyword rankings, increase organic visibility, and drive more traffic from search results.
