How to Add Drip Email Marketing SPF Records to DNS

Setting up email authentication properly ensures your marketing campaigns land in the inbox instead of the spam folder. When using Drip for your email marketing campaigns, publishing a correct Sender Policy Framework (SPF) record is essential to authorize their servers to send mail on your behalf. Without this configuration, mail servers may flag your broadcasts as suspicious or outright reject them.

To build and format your DNS entries correctly without syntax errors, you can use the SPF Record Generator to instantly assemble the required mechanisms and modifiers for your domain.

Understanding How Drip SPF Works

SPF is aTXT record published in your domain's DNS zone that lists all authorized IP addresses and third-party senders permitted to dispatch emails using your domain name in the Return-Path or From address. When receiving mail servers get an email claiming to be from example.com, they query the DNS for example.com's SPF record to verify if the sending server's IP address matches an authorized source.

Unlike traditional infrastructure where you own the mail servers, automated marketing platforms like Drip handle delivery through their own dedicated infrastructure. Because of this, you must delegate sending permissions to them using their specific include mechanism.

The Drip Include Mechanism

Drip relies on a specific domain inclusion to authorize their mail transfer agents. The standard include statement for Drip is:

include:mailgun.org

Note: Drip utilizes industry-standard delivery infrastructure, which means their include mechanism points to their authorized sending partner domains. Always verify the exact include string inside your Drip account settings before publishing. When added to your existing DNS TXT record, this tells receiving servers to evaluate the SPF records of that included domain as part of your authorized sender list.

How to Find Your Drip Sending Domain Settings

Before making changes to your DNS provider, locate your sender profile settings inside your Drip dashboard.

1. Log into your Drip account.
2. Navigate to your account settings or user profile menu, typically found in the top-right corner or bottom-left sidebar depending on your dashboard version.
3. Look for the Email Deliverability, Domain Setup, or Sender Signatures section.
4. Locate the domain authentication or SPF section where Drip displays the exact DNS records required for your specific account setup.

Keep this window open or copy the exact strings to your clipboard so you can paste them accurately into your DNS manager.

Step-by-Step Guide to Adding the Drip SPF Record to DNS

Adding an SPF record requires access to the DNS management console of the registrar or hosting provider where your domain's name servers are hosted (such as Cloudflare, GoDaddy, Namecheap, or Route53).

Step 1: Check for Existing SPF Records

A domain is only allowed to have one active SPF TXT record. If you already have an SPF record for your domain (for example, to support Google Workspace or Microsoft 365), you must append Drip's include mechanism to that existing record rather than creating a second one.

Run a quick query from your terminal using dig to check your current setup:

dig example.com TXT +short

Sample output:

"v=spf1 include:_spf.google.com ~all"

If you see an existing record, you will edit it. If no SPF record exists, you will create a new one.

Step 2: Access Your DNS Management Console

Log in to your DNS hosting provider. Navigate to the domain management area and locate the DNS Zone Editor, DNS Manager, or Manage DNS screen. Menu names may differ slightly depending on your provider, but you are looking for the table or list where A, CNAME, and TXT records are displayed.

Step 3: Create or Edit the SPF TXT Record

If you are creating a brand new record, click Add Record, select TXT as the record type, and use the following values:

• Host / Name / Alias: @ (or leave blank, representing your root domain example.com)
• Value / Answer / Content: v=spf1 include:mailgun.org ~all
• TTL (Time to Live): Set to 3600 seconds (or default/automatic)

If you are merging Drip with an existing provider (such as Google Workspace), you must combine the include statements into a single string:

• Value / Answer / Content: v=spf1 include:_spf.google.com include:mailgun.org ~all

Scenario	Correct SPF Record Syntax
Drip Only	v=spf1 include:mailgun.org ~all
Drip + Google Workspace	v=spf1 include:_spf.google.com include:mailgun.org ~all
Drip + Microsoft 365	v=spf1 include:spf.protection.outlook.com include:mailgun.org ~all

Click Save or Add Record to commit the changes.

Step 4: Verify Your SPF Record Propagation

DNS changes take time to propagate globally. Once saved, test your record using command-line tools or online utilities to ensure it is publicly visible and syntactically valid.

Run nslookup on Windows or PowerShell:

Resolve-DnsName -Name example.com -Type TXT

Or use dig on macOS and Linux:

dig example.com TXT

Ensure the output returns your exact concatenated string without syntax errors or formatting breaks.

Common Mistakes and How to Fix Them

Even experienced engineers occasionally make configuration errors when updating SPF records. Avoid these common pitfalls:

• Multiple SPF Records: Creating two separate TXT records starting with v=spf1 will cause both records to fail validation due to a permanent policy error (permerror). Always merge all required third-party services into a single TXT record.
• Exceeding the DNS Lookup Limit: The SPF specification restricts domains to a maximum of 10 recursive DNS lookups. Each include, a, mx, or ptr mechanism counts toward this limit. If you have too many services, lookups fail. Remove unused services or flatten your SPF record if necessary.
• Typos in Include Strings: A simple typo like incude:mailgun.org or missing a colon will break authentication entirely. Double-check every character against Drip's official documentation.
• Using the +all Modifier: Ending your record with +all permits every server on the internet to send mail as your domain, effectively destroying your email security. Always use ~all (softfail) or -all (hardfail).

Pre-Deployment Checklist

Review this quick checklist before confirming your setup with Drip:

• Verified no other duplicate v=spf1 TXT records exist.
• Included the exact Drip-approved authorization string.
• Kept total DNS lookups well under the 10-lookup limit.
• Used the correct ~all or -all termination modifier.
• Tested propagation using dig or nslookup commands.
• Triggered validation inside the Drip dashboard.
