Setting Up Your Email

Why Domain Setup Matters

Emails sent from a verified domain have dramatically better deliverability. Without it, your emails may land in spam — or never arrive at all.

Email providers judge the sender's domain — Gmail, Outlook, and Apple Mail use your sending domain's reputation to decide if your email belongs in the inbox or the spam folder.
Unverified domains look suspicious — If Jtek sends emails on behalf of your business without domain verification, those emails appear as if they're coming from a shared, unverified IP — a red flag for spam filters.
Authentication records (SPF, DKIM, DMARC) prove legitimacy — These DNS records tell receiving servers that Jtek is authorized to send on your behalf. Without them, your emails fail authentication checks.
Domain reputation builds over time — Once verified, every email you send that gets opened and clicked contributes positively to your domain's sender score. A higher score means better inbox placement.
Setup takes about 15 minutes — The process involves adding a few DNS records in your domain registrar (where you bought your domain). Jtek provides the exact values — you just copy and paste them.

Tip: Even if you're only sending a few emails a week, domain setup protects your business reputation. It's the single most impactful step you can take for email deliverability.

Adding Your Sending Domain

The first step is telling Jtek which domain you want to send email from. This is usually the same domain as your business website.

Go to Settings in the left sidebar — Click the gear icon at the bottom of the navigation panel.
Find "Email Services" in the Settings menu — Scroll down the settings list until you see Email Services. Click it to expand the submenu.
Click "Sending Domains" — This section lists all domains connected to your account. It will be empty on first setup.
Click "+ Add Domain" — A dialog will appear asking you to enter a domain name.
Enter your domain — Type in your business domain (e.g., yourbusiness.com). Do not include "www" or "https://" — just the bare domain. Click Add to proceed.

Tip: You can add multiple sending domains if you have more than one business. Each domain is verified separately and can have its own default From address.

Adding DNS Records

After adding your domain, Jtek will show you the DNS records you need to add in your domain registrar. This step proves to email servers that Jtek is authorized to send on your behalf.

Copy the DNS records Jtek provides — You'll see three types: SPF (TXT record), DKIM (TXT or CNAME record), and DMARC (TXT record). Screenshot or keep this page open while you work in your registrar.
Log in to your domain registrar — This is where you bought your domain: GoDaddy, Namecheap, Cloudflare, Google Domains, or similar. Go to the DNS management section for your domain.
Add the SPF record — Create a new TXT record. The "Host" or "Name" field is usually "@" or your domain. Paste the SPF value exactly as shown in Jtek.
Add the DKIM record — Create another TXT or CNAME record (Jtek will specify which). The Host field will be something like "jtek._domainkey". Paste the value exactly.
Add the DMARC record — Create a final TXT record with Host "_dmarc". Paste the value from Jtek. Save all records when done.

Important: Copy DNS record values exactly as shown — even a single character difference will cause verification to fail. If your registrar has an existing SPF record, you'll need to merge the values rather than creating a second SPF record.

Verifying Your Domain

Once you've added the DNS records in your registrar, come back to Jtek and trigger a verification check. DNS changes can take time to propagate across the internet.

Return to Settings → Email Services → Sending Domains — Find your domain in the list. It will show "Pending" status until verified.
Click the "Verify" button — Jtek will check your domain's DNS records in real time. If all three records are detected correctly, the status changes to "Verified."
If verification fails, wait and retry — DNS propagation can take anywhere from a few minutes to 24 hours. Don't panic if it fails immediately after adding the records — try again in 30 minutes.
Double-check your records if it keeps failing — Log back into your registrar and compare each record character-by-character against what Jtek shows. Common mistakes: extra spaces, wrong record type, wrong host name.
Once verified, the domain shows a green "Verified" badge — You're now authorized to send email from this domain through Jtek. All future email sends will carry proper authentication.

Tip: Use a free tool like MXToolbox (mxtoolbox.com/SuperTool.aspx) to check if your DNS records are live before retrying verification in Jtek. This saves time troubleshooting.

Setting a Default From Name and Address

Once your domain is verified, set the name and email address your contacts will see in their inbox. This is one of the most important trust signals in email marketing.

Go to Settings → Email Services → Sending Domains — Click on your verified domain to open its settings.
Set your "From Name" — This is the name recipients see (e.g., "Jesse at Jtek" or "The Riverside Team"). Use a real name — emails from a person outperform emails from a generic business name.
Set your "From Email" — Choose an address on your verified domain (e.g., hello@yourbusiness.com, jesse@yourbusiness.com). This must match the domain you verified — you cannot use a Gmail or Outlook address here.
Set a "Reply-To" address (optional) — If you want replies to go to a different address than your From address, enter it here. This is useful if you monitor a shared inbox.
Click Save — These settings become the default for all campaigns and automated emails sent through Jtek. You can override them per-campaign when needed.
