Overview
SmartrMail automatically sets your "from" address to the email you use for your Shopify, BigCommerce, WooCommerce, or Neto account. Since Gmail and Yahoo now require proper authentication for senders, it's strongly recommended to send from a custom domain that matches your business's website, rather than a generic or default address.
Important: changing your from-address alone will still work — your emails will still send. But without also authenticating your custom domain (SPF/DKIM/DMARC), you're taking on real deliverability risk: Gmail and Yahoo have no way to verify you actually control that domain, which can make your emails look less trustworthy, not more. Treat the domain authentication step below as a required part of this process, not an optional follow-up.
Why update your from-address and domain settings?
Updating your from-address and setting up a custom sending domain:
Improves email deliverability
Reduces the chance of your emails being marked as spam
Increases trust and credibility with your recipients
How to update your 'from' address
Click the dropdown menu in the top right corner of your account, then select Settings.
In the Settings menu, go to Email Settings.
Update your Email ID to an address that uses your custom domain (e.g.
[email protected]).
Set up your custom sending domain (required)
Changing your from-address is only half the process. To actually get the deliverability benefit — and avoid the risk described above — you need to authenticate your custom domain too.
Follow our Custom Sending Domain setup guide to verify and authenticate your domain. This is the step that actually proves to Gmail and Yahoo that you control the domain you're sending from.
FAQs
Do I need to do anything besides changing my from-address?
Yes — changing your from-address alone will still work, but it's strongly recommended (and treated as a required part of this process) to also authenticate your custom domain. Without it, you're taking on real deliverability risk, since Gmail and Yahoo have no way to verify you actually control the domain you're sending from.
Will my reply-to address change too?
You don't need to worry about this separately — reply-to isn't a stored setting at all. It's calculated live every time an email sends, based on your current from-address. If you're not using a custom verified sending domain, your reply-to is automatically set to match your current from-address. If you are on a custom domain, no reply-to header is set at all, so replies default to whatever your from-address is at the time.
How long until my new from-address takes effect?
The from-address setting itself is an account-level change, not a DNS record, so it should take effect quickly. If you're also setting up domain authentication (SPF/DKIM/DMARC) as part of this process, those DNS records can take up to 24–48 hours to propagate — this is standard for any DNS change, not specific to SmartrMail.
Does this affect emails that are already scheduled?
Yes — your from-address isn't locked in when a campaign or automation is scheduled. It's pulled live from your account settings at the moment each email actually sends. So if you change your from-address today, anything scheduled for later — even sends already queued — will go out using your new from-address, not the one that was set when it was originally scheduled.
What plan do I need to change my from-address?
This is available on all SmartrMail plans.
