How to add follow-up emails to a sequence

Step-by-step on how to add a follow-up and email thread

Learning Objective

By the end of this tutorial, you'll know how to add follow-up emails to your campaigns, set strategic timing between steps, create threaded conversations that stay in the same inbox thread, and structure sequences that increase reply rates through value-driven touchpoints.


Why This Matters

Single emails get lost. Multi-step sequences with strategic follow-ups increase reply rates by 3-5x compared to one-off emails. Most prospects don't respond to the first email. Not because they're uninterested, but because they're busy. Follow-ups keep you top-of-mind, demonstrate persistence, and give prospects multiple opportunities to engage when timing works for them.


Prerequisites

Before you start, make sure you have:

  • A campaign created with at least one initial email step

  • Understanding of your target audience's typical response timing

  • Content planned for your follow-up emails (value-adds, different angles, or urgency)


Core Lesson — Step-by-Step Workflow

Phase 1: Understand Sequence Structure

What is a sequence?

A sequence (also called a drip campaign) is a series of scheduled emails sent automatically over time. It starts with your initial outreach email and continues with follow-up emails sent at strategic intervals.

What is a follow-up email?

A follow-up email is sent to leads who haven't replied to previous emails in the sequence. These are automatically triggered based on the delays you set.

💡 Key concept: Follow-ups only send to non-responders. If someone replies at any step, the sequence typically stops (depending on your campaign settings).

Example sequence structure:

  • Day 1: Initial email introducing your solution

  • Day 4: Follow-up sharing a case study (sent only if no reply to previous email)

  • Day 8: Follow-up with a different value angle (sent only if no reply to previous emails)

  • Day 12: Final follow-up with urgency or breakup message


Phase 2: Add Your First Follow-Up Email

Step 1: Access your campaign

Go to Campaigns, then select the campaign you want to edit.

Open Campaigns and select a campaign

Step 2: Open the Sequence tab

At the top of the campaign page, click Sequence. This opens the flow where your steps are built.

You should see your existing sequence structure, including your initial email step.

Step 3: Add a new email step

From the Sequence view, click + Add step.

In the Sequence view, click Add step

In the step picker, keep Steps selected, then choose Email as the step type.

Choose Email from the step picker

A new email step is added to your sequence.

Step 4: Set the delay

Click the wait time above the new email step, then set the number of days to wait before sending the follow-up.

Edit the wait time for the follow-up step

Common delay strategies:

  • 3-4 days for high-urgency B2B outreach

  • 5-7 days for considered purchases or executive-level contacts

  • 2-3 days for event-based or time-sensitive campaigns

💡 Why timing matters: Too soon feels pushy, too long loses momentum. Test different delays to find what works for your audience. If you set up a delay to 0 days, lemlist will send a follow-up email immediately after.

Step 5: Write your follow-up email content

Select the new email step, then write your follow-up in the editor on the right. If this email is part of an existing thread, do not change the subject line.

Write the follow-up email and keep the thread intact

Follow-up best practices:

  • Add value - Don't just say "checking in." Share a resource, insight, or different angle.

  • Reference the previous email - Briefly acknowledge that you've reached out before

  • Keep it short - Follow-ups should be 3-5 sentences maximum

  • Change the approach - Don't repeat the first email; try a different value proposition

💡 Storytelling technique: Build on a theme or joke from your first email to create continuity and show you're a real person.

Step 6: Save and verify the follow-up step

Your changes are saved in the sequence editor. Review the left-hand flow to confirm your follow-up step appears in the right place with the correct delay.

Verify the new follow-up step in the sequence

Verify: You should see your follow-up step in your sequence with the delay displayed.


Phase 3: Add Additional Follow-Ups

Step 7: Add a second follow-up

Click the + Add step button below your first follow-up.

Add another email step.

Set a new delay (for example, 4 days after the previous step).

Write your second follow-up with a different angle or value-add.

If you want it to stay in the same thread, leave the subject line unchanged or blank, depending on how the thread is configured.

💡 Sequence length best practice: 3-5 emails is optimal for most B2B sequences. More than 5 risks diminish returns unless you have very high-value prospects.

Step 8: Repeat to build your full sequence

Continue adding follow-up steps until you've built your complete sequence.

Each step should:

  • Have a strategic delay

  • Provide unique value or a new angle

  • Stay in the same thread when appropriate

  • Get progressively shorter and more direct

Step 9: Craft your final email

Your last email should either:

  • Breakup email: "Seems like now isn't the right time. I'll reach out in [X months]."

  • Final value offer: "Last chance to access [specific benefit]"

  • Permission question: "Should I close your file or is there interest in staying in touch?"

💡 Breakup emails often generate the most replies because they create urgency and show you're moving on.


Phase 4: Optimize Your Sequence Structure

Step 10: Review the full sequence flow

Look at your complete sequence from top to bottom.

Check that:

  • Delays make sense (increasing intervals usually work best)

  • Each email provides a different value or angle

  • The sequence tells a coherent story

  • The final email creates urgency or closure

Step 11: Preview email threading

Click Preview in the email editor to see how your follow-up will appear.

Open Preview from the email editor

💡 Troubleshooting note: If you see blank subject lines in preview mode, this can be normal for threaded follow-ups. The sent email will use the original thread behavior configured in your sequence.


Practical Application / Real-Life Example

SaaS Sales Sequence (5-Touch Sequence)

Context: Selling marketing analytics software to CMOs and marketing directors

Step 1 - Day 1: Initial Outreach

  • Subject: "Quick question about #{{companyName}}'s marketing attribution"

  • Content: Problem-focused question referencing their recent campaign or company news

  • Length: 80 words

Step 2 - Day 4: Value-Add Follow-Up

  • Subject: [Same thread]

  • Content: "Not sure if you saw my note below. Thought you might find this case study relevant, we helped a similar company increase attribution accuracy by 40%." + link to case study

  • Length: 50 words

Step 3 - Day 8: Different Angle

  • Subject: [Same thread]

  • Content: "Different approach, instead of attribution, are you tracking customer journey touchpoints effectively? That's where most CMOs we work with see the biggest blind spot."

  • Length: 40 words

Step 4 - Day 11: Social Proof

  • Subject: [Same thread]

  • Content: "Quick update: Just closed a deal with [recognized brand in their industry]. They had the same attribution challenges. Would a 15-min call make sense to see if we're a fit?"

  • Length: 35 words

Step 5 - Day 15: Breakup Email

  • Subject: [Same thread]

  • Content: "Seems like now isn't the right time. I'll check back in Q3. If anything changes, you have my info below."

  • Length: 25 words

Results:

  • 42% open rate across the sequence

  • 18% reply rate (vs. 4% with single email)

  • 67% of replies came from Steps 3-5 (not the initial email)

  • The breakup email (Step 5) generated 25% of total replies

Key success factors:

  • Each email provided a different value or angle

  • Progressive urgency (soft → direct → breakup)

  • Decreasing length (80 → 25 words)

  • Threaded in inbox (maintained context)


Troubleshooting & Pitfalls

Issue: Follow-ups are being sent to leads who already replied

Root cause: Stop conditions not configured in campaign settings

Fix:

  • Go to campaign SettingsStop sending messages when lead...

  • Enable "Replies to email" so the sequence auto-stops on reply

  • See: Stop campaigns when leads engage (link to related article)

Issue: Follow-ups appearing as separate emails, not in the same thread

Root cause: The subject line was changed on a threaded follow-up

Fix:

  • Edit each follow-up step

  • Keep the existing thread settings intact

  • If lemlist shows a warning that changing the subject line will break the thread, leave it unchanged

  • Do NOT add "RE:" manually. lemlist handles threading automatically

Issue: Preview looks different from the live email thread

Root cause: Preview mode is only a representation of the follow-up step

Fix:

  • Use Preview to check formatting and content

  • If needed, send a test email to yourself to confirm how the thread will appear in a real inbox

Issue: Follow-ups are being sent too close together or all at once

Root cause: Delays not properly configured or set to 0 days

Fix:

  • Edit each step and verify the delay is set correctly

  • If you want time between messages, make sure the wait step is greater than 0 days

  • lemlist respects your sending schedule. If delays land outside sending hours, they'll queue for the next available window

Issue: The last follow-up never sends

Root cause: Campaign completed or lead reached the end of the sequence before the delay finished

Fix:

  • Check campaign status. If "Completed," all leads are finished

  • Verify the lead didn't reply earlier (check lead activity log)

  • Ensure the delay for the final step isn't longer than your campaign timeline


Follow-Up Content Strategies

Strategy 1: Value Ladder

Each follow-up provides progressively more valuable content:

  • Email 1: Identify the problem

  • Email 2: Share a relevant insight or stat

  • Email 3: Provide a case study or success story

  • Email 4: Offer a specific solution or demo

  • Email 5: Final value offer or breakup

Strategy 2: Multi-Threading (Different Angles)

Each follow-up approach follows from a different angle:

  • Email 1: Efficiency angle ("Save 10 hours per week")

  • Email 2: Risk angle ("Most companies miss this compliance requirement")

  • Email 3: Revenue angle ("Increase conversions by 25%")

  • Email 4: Social proof angle ("Your competitor just implemented this")

  • Email 5: Timing angle ("Pricing increases next month")

Strategy 3: Story Building

Build a narrative across emails:

  • Email 1: "I noticed something about #{{companyName}}..."

  • Email 2: "So I dug deeper and found..."

  • Email 3: "Turns out, 73% of companies in your space face the same issue..."

  • Email 4: "Here's how three of them solved it..."

  • Email 5: "Curious if this resonates with you?"

Strategy 4: The Pattern Interrupt

Break the typical sales sequence pattern:

  • Email 1: Standard value proposition

  • Email 2: "Forget what I said in my last email..."

  • Email 3: Contrarian take or controversial opinion

  • Email 4: "Okay, back to being professional..."

  • Email 5: Honest/vulnerable breakup email


Tips for Optimization

Test delay intervals - Run small batches with different delays (3-day vs. 5-day vs. 7-day) to see what generates the best response rates for your audience.

Personalize follow-ups - Use variables like #{{firstName}}, #{{companyName}}, or custom fields to make follow-ups feel tailored, not automated.

Vary the hook - Don't repeat "Just following up" or "Circling back." Each email should have a fresh opening that could stand alone.

Track per-step performance - Monitor which steps get the most replies in your analytics. If Step 3 consistently performs best, consider leading with that angle in future sequences.

A/B test email length - Try short (2-3 sentences) vs. longer (5-7 sentences) follow-ups to see what your audience responds to.

Use the breakup email - Don't skip the final email. Breakups often generate 20-30% of total replies by creating urgency and showing respect for their time.

Match follow-up frequency to buying cycle - Enterprise sales with 6-month cycles can have 7-10 day delays. SMB sales with 2-week cycles need 2-3 day delays.

Maintain thread integrity - Never break the thread by changing the subject line on threaded follow-ups. Threading is one of the most powerful features for appearing organized and professional.

Front-load your sequence - Put your strongest value in Steps 1-2. Steps 4-5 should be shorter and more direct since most responses come earlier.

Update based on triggers - If something changes (company announces funding, new exec joins, industry news), add a triggered follow-up referencing that event.
