How to merge or update existing SPF records

Introduction

In email authentication, the SPF record (Sender Policy Framework) specifies which mail servers are authorized to send emails on behalf of a domain. With ActiveCampaign, when you set up your sending domain, this process includes setting up the correct SPF records automatically, which means you often do not need to create or modify an SPF record to work with ActiveCampaign.

However, manually setting up ActiveCampaign SPF records for your From domain can provide added benefits, particularly regarding enhancing your email deliverability. If you opt to manage your SPF records manually, it is crucial to understand that a domain can only have one valid SPF record. This article explains the process of updating or merging existing SPF records to ensure compliance and maintain email functionality effectively.

How to access this feature

To access and manage your SPF records, you will typically work within your domain's DNS settings. This can be accessed through your domain registrar or hosting provider where DNS records can be modified.

Step-by-step instructions

Adding ActiveCampaign’s Include to an Existing SPF Record

If you already possess an SPF record and need to add ActiveCampaign as an email sender, you can do this by adding the required include statement to the current record.

1. Retrieve your existing SPF record. For example:

  ```
  v=spf1 include:_spf.google.com -all
  ```

2. Add the include statement for ActiveCampaign:

  ```
  v=spf1 include:_spf.google.com include:emsd1.com -all
  ```
  - Ensure that the new string is placed before the **-all** part.
  - Do not incorporate unnecessary spaces; each string should be separated by a single space.
  - Ensure the recording starts with **v=spf1**.

Merging Existing SPF Records

If you have multiple SPF records, you will need to merge them into a single record, as having dual or more SPF records is invalid.

1. Identify your existing SPF records:

  ```
  v=spf1 ip4:20.33.1.86/32 include:_spf.google.com -all
  v=spf1 include:emsd1.com -all
  ```

2. Delete one record and modify the other to combine both sets of information:

  ```
  v=spf1 include:emsd1.com ip4:20.33.1.86/32 include:_spf.google.com -all
  ```

Important Points to Remember

- The SPF record may contain various qualifiers (like **-all**, **~all**, **?all**, or **+all**). It is recommended to use either **~all** (soft fail) or **-all** (fail). - Merging SPF records offers a perfect chance to tidy the list. Remove outdated includes or strings. - Since SPF records are processed from left to right, place the most frequently used includes at the top. - Do note that SPF records have a limit of 10 DNS lookups; thus, you may need to optimize accordingly.

Configuration options and settings

While modifying SPF records, it is crucial to pay attention to the following configuration options: - **include**: Specifies other domains that are allowed to send emails on your behalf. - **ip4**: Designates valid IP addresses that can send emails for your domain. - **-all**: Indicates that emails not matching the previous mechanisms should be rejected (hard fail). - **~all**: Soft fail, indicating emails not matching should be treated with caution but still accepted.

Best practices and tips

- Always have a single SPF record per domain to avoid email delivery issues. - Regularly review and update your SPF record to remove any outdated or unused includes. - Utilize the include directive wisely to aggregate services you use for email sending. - Test your SPF records after modifying them using online SPF record testers to confirm they are valid.

Troubleshooting

If issues arise with email delivery following SPF record updates, check the following: - Ensure there are no conflicting SPF records for your domain. - Validate your SPF record with an online tool to ensure it adheres to SPF standards. - Confirm that all necessary senders and services are included in your SPF record.
