Where to find and change your sender email in Klaviyo

To change the sender email address in Klaviyo, go to Account in the bottom left corner, then select Settings, and click Email Accounts. You'll see a list of email addresses currently set up for your account. Click the three-dot menu next to the email you want to change, then select Edit. From there you can update the sender address and save your changes.

The sender email is what appears in your recipients' inboxes as the "From" address. Changing it affects all future campaigns that use that email account, but does not change emails you've already sent. If you want different campaigns to send from different addresses, you'll need to set up multiple email accounts in Klaviyo first.

Key Takeaways

  • Your sender email is changed through Account > Settings > Email Accounts, then clicking Edit next to the address you want to modify.
  • Changing your sender email only affects campaigns you send after the change — past emails keep their original sender address.
  • You can set up multiple sender email addresses in Klaviyo and choose which one to use for each campaign.
  • Your sender email must be verified through your email provider before Klaviyo will send from it, which usually takes a few minutes to a few hours.
  • If you're switching to a new domain, you'll need to add authentication records (SPF and DKIM) to that domain for reliable delivery.

Setting up a new sender email address for the first time

If you're adding a sender email address that doesn't yet exist in your Klaviyo account, start in the same Email Accounts section and click Add Email Account. Enter the email address you want to send from, then Klaviyo will send a verification link to that inbox. You must click the verification link within 24 hours, or the address won't activate.

Once verified, the address appears in your Email Accounts list and you can use it as your sender for any campaign. Klaviyo requires this verification step to confirm you actually own or control the email address — it prevents people from sending campaigns that appear to come from addresses they don't have access to.

Choosing which sender email to use for each campaign

When you create a new campaign or flow in Klaviyo, you'll see a field labeled From Email or Sender Email. Click that field and select from the list of verified email addresses you've already added to your account. This choice is made at the campaign level, so different campaigns can send from different addresses if you have multiple ones set up.

If you want one address to be the default for all new campaigns, you can set a primary email account in your Email Accounts settings. Any campaign you create will automatically use that address unless you manually change it.

Authentication records you may need to add

If you're sending from a new domain (for example, switching from noreply@oldcompany.com to noreply@newcompany.com), Klaviyo will ask you to add SPF and DKIM records to your domain's DNS settings. These are authentication records that tell email providers your domain has authorized Klaviyo to send on its behalf.

You don't add these records in Klaviyo itself — you add them through your domain registrar or hosting provider's DNS management panel. Klaviyo provides the exact records you need to copy. Adding them usually takes a few minutes, but email providers may take up to 24 hours to recognize them. Until they do, your emails may land in spam folders more often.

If you're sending from an address at your own domain (not Gmail, Outlook, or another third-party email service), adding these records is strongly recommended. If you're sending from a Gmail or company email address managed by your email provider, you may not need to add them yourself.

What happens to campaigns already sent from the old address

Changing your sender email does not retroactively change the "From" address on emails you've already sent. If you sent a campaign yesterday from sales@company.com and today change your sender to support@company.com, yesterday's email still shows sales@company.com in recipients' inboxes.

This also means your email history and reputation stay attached to the old address. If you've built up a good sending reputation with sales@company.com, switching to a brand-new address means you're starting over with email providers' trust systems. For this reason, many teams keep the same sender address for months or years rather than switching frequently.

Troubleshooting sender email problems

If you can't find your email address in the From Email dropdown when creating a campaign, it probably hasn't been verified yet. Go back to Email Accounts and check whether the address shows a "Pending" or "Unverified" status. If it does, check the inbox for that address and click the verification link Klaviyo sent. If you don't see the email, ask Klaviyo to resend it by clicking Resend Verification in the Email Accounts section.

If your campaigns are bouncing or going to spam after you change your sender address, the most common cause is missing SPF or DKIM records. Check your Email Accounts settings to see whether Klaviyo is showing a warning about authentication. If it is, follow the steps to add those records to your domain's DNS. It can take 24 hours for the change to take effect, so test with a small segment first before sending to your full list.

Frequently Asked Questions

Can I send from multiple email addresses in the same campaign?

No. Each campaign has one sender email address. If you need different recipients to receive emails from different addresses, you'll need to create separate campaigns or use Klaviyo's segmentation to split your audience and send them through different flows with different sender addresses.

What if I delete an email account I've been sending from?

Deleting an email account from Klaviyo does not affect campaigns you've already sent — those emails stay in recipients' inboxes with the original sender address. However, you won't be able to use that address for new campaigns. If you delete an address by mistake, you can add it back and verify it again.

Do I need to verify my sender email every time I change it?

Only if you're adding a completely new email address to Klaviyo for the first time. If you're just switching which verified address you use for a campaign, no new verification is needed. The address must have been verified once when you first added it to your account.

Will changing my sender email affect my email deliverability?

Switching to a brand-new email address means you're starting with no sending history, so email providers may be more cautious about your messages at first. Adding SPF and DKIM records helps build trust quickly. If you're switching to an address at a new domain, expect slightly lower inbox placement for the first week or two until providers recognize the authentication records.
