Sender Profile, From Email & Domain Authentication (DKIM)

When sending emails with Strikingly, you must set a Sender Profile. These details will be shown when the recipient opens your email in their inbox.

In the From Email (Reply-to) field, you may use a custom email address in order to receive replies from your email recipients. This From Email (Reply-to) must follow some important rules:

  1. If the email address is on a free service (e.g. Gmail, Hotmail, Yahoo), your emails are more likely to be marked as spam! We strongly recommend using a custom domain for this instead.
  2. If the email address is on a domain that is managed on Strikingly, you don’t need to do anything else! We’ll handle the validation automatically.
  3. If the email address is on a domain that is managed on a third-party registrar (e.g. Godaddy, Namecheap, etc), then you’ll need to add DKIM authentication to your domain in order to properly send emails from that email address. To do this, follow the instructions below:


Except for the following two situations:

  • If you are using an email domain hosted on Strikingly, your domain has already been authenticated and recipients won't see "via" in your email —— so no more action needed.
  • Email addresses from free services (Gmail, Yahoo, Hotmail, etc) cannot be authenticated and are more likely to be marked as spam or junk. We recommend using a custom domain.

You'll learn why this authentication is important and how to do it exactly in this article.


Benefits of Email Domain Authentication

Large inbox service providers (ISPs) like Google, Yahoo, and Microsoft detect incoming emails for spam or spoofed addresses by a tool named Domainkeys Identified Mail (DKIM). Emails that fail the detection will be marked as spam or junk. Authenticating your domain will help to pass their detection.

To improve your deliverability, Strikingly automatically adds default DKIM authentication to all your email campaigns. Our default authentication shows your recipient’s internet service provider that your email comes from a legitimate sender, and it helps your email arrive in their inbox. That's why you'll see "via" in the "From" field of the emails you sent. 

However, if you want to remove the “via” in your emails and still ensure your emails reach your recipients' inboxes, you must add DKIM authentication to your domain. 


How To Authenticate Your Domain For Emails (DKIM)

Please follow the steps below. If you need more help, you can send this tutorial to your registrar’s customer service or reach out to us for support!


Step 1: Find Your Registrar's DNS Settings

1. Sign in to your domain registrar's account.

(If you're not sure who your domain provider is, go to and search for your domain name. You may find your domain provider in Registrar Information. If not, try to reach out to your hosting service.)

2. Find the DNS Settings for your domain.

(It can also be called DNS, DNS manager, DNS records, host record, zone settings, zone file, etc. But do not change your nameserver!)


Step 2: Check the DNS records you need for your domain authentication in Strikingly Site Editor

Go back to the Strikingly site editor, to the Email Notifications page, and click “authenticate your email”. In the popup, you will see four entries that need to be added to your DNS record.mceclip4.png



Step 3: Add Three CNAME Records And One TXT Record

In your domain registrar's DNS settings, add the CNAME and TXT records for 4 entries given to you in Strikingly popup. (different registrars have different name or labels):

Alias/Host/Name Type Value/Record/Address/Points to/Data TTL
  CNAME   Default
  CNAME   Default
  CNAME   Default
  TXT   Default



Step 4: Wait for the Records to Take Effect

Now that you've set up the domain records, please allow up to 24-48 hours for the changes in the domain records to take effect globally. 

We’ll automatically detect your DNS records for the required changes.


After we detect the correct values, you’ll see a green message here, indicating that you've successfully set up DKIM authentication for your domain. The "via" will be removed from your email "From" field.


If we can’t detect the correct values after 24 hours, you’ll be notified by email. You’ll need to make sure that you’ve completed Steps 1-4 and try again. As always, you can contact us for support!
