How to Use Smartlead Premium Deliverability

Here’s how to use it step by step.

Watch Premium Deliverability in action:

Now let’s break down each step.

Step 1: Enable SmartDelivery Warmup

Go to your email account settings and toggle on “Email Warmup.”

For existing accounts, follow the step-by-step DNS setup guide inside the platform.

Here’s what this looks like:

✓ Checkpoint: All three records should show a green checkmark in the DNS health panel.

Step 3: Set Sending Limits and Schedule

Cap daily sends per inbox at a safe volume — Smartlead recommends ramping up gradually over 2–4 weeks.

💡 Pro Tip: Run warmup for at least 14 days before sending any cold campaigns from a new domain.

Step 1: Generate Your API Key

Here’s what this looks like:

✓ Checkpoint: Send a test API call and confirm you receive a 200 OK response.

Step 3: Build an Automated Lead Flow

Set up a trigger — for example, when a lead fills a form, automatically add them to a Smartlead campaign.

Map your CRM fields to Smartlead custom fields for full personalization.

✅ Result: Leads flow automatically from your sources into active campaigns without any manual work.

💡 Pro Tip: Use webhooks to trigger real-time notifications in Slack when a lead replies or books a meeting.

How to Use Smartlead Email Warmups

Email Warmups lets you build a strong sender reputation before launching cold campaigns.

Here’s how to use it step by step.

Watch Email Warmups in action:

Now let’s break down each step.

Step 1: Add Your Email Account to Warmup

Go to Email Accounts, select the account you want to warm, and click “Enable Warmup.”

Choose a warmup ramp speed — slow, medium, or aggressive — based on your domain age.

Step 2: Monitor Warmup Health Scores

Check your inbox health score in the Warmup dashboard daily during the first two weeks.

Smartlead shows spam placement rates, inbox rates, and reply engagement from the warmup network.

Here’s what this looks like:

✓ Checkpoint: Aim for an inbox placement rate above 90% before starting live campaigns.

Step 3: Keep Warmup Running During Campaigns

Never turn off warmup once campaigns are live — it continuously protects your sender score.

Smartlead’s warmup emails automatically filter out of your real replies so they don’t clog your inbox.

✅ Result: Your email accounts maintain a healthy sender reputation even as campaign volume scales up.

💡 Pro Tip: Run warmup in parallel across all inboxes in a campaign to keep their health scores synchronized.

Now let’s break down each step.

Step 1: Open the Master Inbox

Click “Master Inbox” in the left sidebar of your Smartlead dashboard.

All replies from every connected account appear in a single feed.

Step 2: Categorize Replies with AI Labels

Smartlead’s AI automatically tags each reply as “Interested,” “Not Interested,” or “Meeting Booked.”

Use filters to surface only the hot leads that need immediate follow-up action.

Here’s what this looks like:

✓ Checkpoint: Interested replies should appear at the top of the filtered view.

Step 3: Reply and Move Leads to Next Steps

Reply directly from the Master Inbox without switching between email accounts.

Move converted leads to your CRM via the built-in integration or webhook.

✅ Result: You handle all prospect communication from one screen, with zero missed replies.

💡 Pro Tip: Set up AI-powered auto-replies for out-of-office responses so follow-ups resume automatically when prospects return.

How to Use Smartlead Customized White Labelling

Customized White Labelling lets you rebrand the Smartlead platform with your own logo, domain, and colors.

Here’s how to use it step by step.

Watch Customized White Labelling in action:

Now let’s break down each step.

Step 1: Access White Label Settings

Go to Settings → White Label in your Smartlead account.

This feature is available on higher-tier plans — check your plan includes white labelling.

Step 2: Upload Your Branding Assets

Upload your logo, set your brand colors, and enter your custom domain for the client-facing portal.

Point your domain’s CNAME record to Smartlead’s servers to activate the custom URL.

Here’s what this looks like:

✓ Checkpoint: Visit your custom domain and confirm it loads the branded Smartlead interface.

Step 3: Invite Clients to the White-Labeled Portal

Send client login links using your custom domain — they’ll never see the Smartlead branding.

Manage client sub-accounts and permissions from your main agency dashboard.

✅ Result: Clients experience a fully branded outreach platform that looks like your own product.

💡 Pro Tip: White labelling is ideal for agencies — charge clients a monthly SaaS fee for access to your branded portal.

How to Use Smartlead Follow-Up Automation

Follow-Up Automation lets you send the right follow-up message based on how a prospect interacted with your email.

Here’s how to use it step by step.

Watch Follow-Up Automation in action:

Now let’s break down each step.

Step 1: Build Your Email Sequence

In Campaign Settings, click “Add Step” to add each follow-up email to your sequence.

Set the delay between steps — typically 2–4 days between each follow-up.

Step 2: Set Trigger-Based Conditions

Choose what action triggers each follow-up — no reply, opened but no click, or link clicked.

Configure “Stop on Reply” so Smartlead pauses the sequence the moment a prospect responds.

✓ Checkpoint: Preview the full sequence flow in the campaign builder before activating.

Step 3: Personalize Each Follow-Up Step

Use spintax and custom fields to make each follow-up feel personal — not templated.

Reference the previous email naturally: “Just following up on my note from last Tuesday.”

✅ Result: Your sequences run on autopilot, following up with every prospect at the right moment without manual intervention.

💡 Pro Tip: Most conversions happen between follow-up 3 and 7 — plan sequences of at least 5 steps for best results.

How to Use Smartlead Email Verification

Email Verification lets you remove invalid addresses before sending to protect your sender score.

Here’s how to use it step by step.

Step 1: Upload Your Lead List

Go to Leads → Import and upload your CSV file with prospect email addresses.

Map the CSV columns to Smartlead’s standard fields — first name, last name, email, company.

Step 2: Run Verification on the List

Select the imported list and click “Verify Emails” to run bulk verification.

Smartlead checks each address for validity, catch-all status, and deliverability risk.

✓ Checkpoint: Review the verification report — aim to remove all “Invalid” and “Risky” results before sending.

Step 3: Export the Clean List to Your Campaign

Filter by “Valid” status and add these leads directly to an active campaign.

Keeping your bounce rate below 2% protects your domain’s long-term sender reputation.

✅ Result: Only verified, deliverable addresses enter your campaigns, keeping bounce rates low.

💡 Pro Tip: Always verify leads sourced from Apollo or LinkedIn before importing — even “clean” lists have 5–15% invalid addresses.

How to Use Smartlead Dedicated Servers

Dedicated Servers lets you send high volumes of email from infrastructure that only you share — boosting control and deliverability.

Here’s how to use it step by step.

Step 1: Activate Dedicated Server in Your Plan

Dedicated servers are available on the higher-tier Smartlead plans — check your plan eligibility.

Contact Smartlead support or upgrade your plan to get a dedicated sending IP assigned.

Step 2: Warm Up Your Dedicated IP

A new dedicated IP starts with zero reputation — run Smartlead’s warmup protocol before live sends.

Gradually increase volume from 50 to 500+ emails per day over 4–6 weeks.

✓ Checkpoint: Your IP’s inbox placement rate should exceed 95% before scaling to full volume.

Step 3: Monitor IP Reputation

Use Smartlead’s server health dashboard to monitor blacklist status and inbox placement rates.

If spam complaints rise, reduce volume immediately and investigate the affected campaign.

✅ Result: You have full control over your sending infrastructure with no shared-IP neighbors hurting your reputation.

💡 Pro Tip: Dedicated servers are best for agencies or teams sending 10,000+ emails per day who need guaranteed inbox placement.

How to Use Smartlead Integrations

Integrations lets you connect Smartlead with your CRM, data enrichment tools, and entire sales stack.

Here’s how to use it step by step.

Step 1: Browse Native Integrations

Go to Settings → Integrations to see all available native connections.

Smartlead connects natively with HubSpot, Salesforce, Pipedrive, and dozens of other CRMs.

Step 2: Connect Your CRM

Click your CRM’s logo, enter your API credentials, and map Smartlead fields to CRM fields.

Set sync rules — for example, push all “Interested” replies as new deals to your CRM pipeline.

✓ Checkpoint: Trigger a test reply in Smartlead and confirm it appears as a new record in your CRM.

Step 3: Automate Data Enrichment

Connect SmartAgents to automatically enrich lead data from Apollo, Clay, or LinkedIn.

Enriched data populates custom fields used for personalization in your email sequences.

✅ Result: Your entire outreach workflow runs automatically — from lead enrichment to CRM sync — without manual work.

Smartlead Common Mistakes to Avoid

Mistake #1: Launching Campaigns on Unwarmed Inboxes

❌ Wrong: Adding a brand-new email account and immediately blasting 200 cold emails per day.

✅ Right: Run Smartlead’s warmup for a minimum of 14 days and reach a health score above 90 before starting any campaign.

Mistake #2: Skipping Email Verification

❌ Wrong: Importing a raw lead list from Apollo without verifying addresses first — bounce rates above 5% will flag your domain.

✅ Right: Always run Smartlead’s email verification on every list before adding leads to a campaign.

Mistake #3: Writing One Generic Follow-Up

❌ Wrong: Sending a single “Just following up” email and giving up when there’s no reply.

✅ Right: Build a 5–7 step sequence with trigger-based conditions in Smartlead — most deals close on follow-up 4 or later.

Smartlead Troubleshooting

Problem: Emails Landing in Spam

Cause: DNS records (SPF, DKIM, DMARC) are misconfigured, or the inbox hasn’t completed the warmup phase.

Fix: Check your DNS health in the Email Accounts panel, correct any failing records, and pause campaigns until warmup health scores exceed 90%.

Problem: High Bounce Rate

Cause: Unverified lead list with a high percentage of invalid or catch-all email addresses.

Fix: Pause the campaign, run email verification on the lead list, remove all invalid and risky addresses, then reactivate.

Problem: Sequences Not Sending

Cause: Campaign is paused, daily sending limit has been reached, or the email account is disconnected.

Fix: Check campaign status, verify the email account is connected and active, and confirm the daily send limit hasn’t been hit in the account settings.

📌 Note: If none of these fix your issue, contact Smartlead support via the live chat in your dashboard.
