Your Welcome Series is arguably the most important email automation you'll ever build. It's the first conversation new subscribers have with your brand, setting expectations and converting cold leads into engaged customers.

This guide shows you exactly how to connect SendX forms popups or footer embeds to an automated Welcome Flow that nurtures every new subscriber into a buyer.


Why Welcome Flows Matter

The data is clear:

  • Welcome emails have higher open rates than standard campaigns

  • Welcome series generate more revenue per email than promotional emails

What a great Welcome Flow accomplishes:

  • Confirms subscription and sets expectations

  • Delivers the promised incentive (e.g., 10% discount code)

  • Introduces your brand story and unique value proposition

  • Showcases best-selling products or most popular content

  • Encourages first purchase with a clear, compelling offer

  • Builds long-term engagement by inviting social follows and preference settings


The Two-Part Setup: Forms + Automation

Connecting forms to a Welcome Flow requires two components working together:

Part 1: Form → List/Tag Assignment When someone submits your form, SendX automatically adds them to a specific list or applies a tag.

Part 2: Automation Trigger A Flow monitors that list or tag and starts the Welcome Drip Sequence when a new contact is added.

Let's build both parts step-by-step.

Step 1: Create Your Welcome Drip Sequence

Before you can trigger a Welcome Flow, you need to build the email series itself.

Recommended Welcome Series structure:

Email

Timing

Purpose

Key Elements

#1: Hello & Incentive

Immediate (within 5 min)

Confirm signup, deliver discount code

Welcome message, discount code (big & bold), CTA to shop, expectations

#2: Brand Story

Day 2 or 3

Build emotional connection

Founder story, mission, what makes you different, social proof

#3: Best-Sellers

Day 5 or 7

Drive first purchase

Top products, customer reviews, urgency (discount expiring soon)

#4: Gentle Nudge (optional)

Day 10

Final conversion push for non-buyers

Last chance for discount, FAQ, customer service contact

To create your Drip Sequence in SendX:

  • Go to Drips → Create New Drip

  • Name it "Welcome Series - [Your Brand]"

  • Add 3-4 emails with appropriate delays between each

  • Design each email with clear subject lines and compelling CTAs

  • Save the Drip (don't activate it yet the Flow will do that)

Step 2: Set Up the Automation Trigger

Now you'll create the Flow that starts your Welcome Drip when someone joins your list.

In SendX:

  1. Navigate to Automations → New Automation

  2. Give it a clear name: "Start Welcome Flow - Form Submissions"

Configure the Trigger: 3. Trigger type: "Contact added to [List/Tag]" 4. Select your list: Choose the list your forms add contacts to (e.g., "Newsletter Subscribers" or "New Signups")

  • Save trigger

Add the Action: 6. Action type: "Start Drip Sequence" 7. Select Drip: Choose your "Welcome Series - [Your Brand]" Drip 8. Delay: Set to "Immediate" (you want Email #1 to send right away) 9. Save action

Activate the Automation: 10. Toggle the automation to Active 11. Confirm it's running by checking the status indicator (green = active)

Step 3: Connect Your Forms

Now that your automation is ready, ensure all your signup forms add contacts to the correct list.

SendX Popup form

If Using SendX Popups:

SendX native popups automatically integrate with lists:

  • Go to Popups → Edit [Your Popup]

  • In Settings → Form Submission Actions:

    • Select "Add to list: Newsletter Subscribers" (or your target list)

    • Optionally apply a tag like "Popup Subscriber" for segmentation

  • Save and publish

The flow:

  • Visitor submits popup → Contact added to list → Automation triggers → Welcome Drip/Workflow starts

SendX embedded form

If Using Embedded Footer or Custom Forms:

For forms embedded on your Shopify site:

  • In Forms → Edit [Your Form]

  • Under Form Settings → Submission Actions:

    • Select "Add to list: Newsletter Subscribers"

  • Copy the embed code

  • Paste into your Shopify theme (see Article 5 for footer embed instructions)

The connection:

  • Visitor submits embedded form → SendX adds contact to list → Automation triggers → Welcome Drip/Workflow starts

Step 4: Test Your Welcome Flow End-to-End

Never skip testing. A broken Welcome Flow means lost revenue and frustrated subscribers.

Testing checklist:

  • Submit your form with a test email address (use an email you can access)

  • Verify the contact was added to the correct list in SendX

  • Check that the automation triggered:

    • Go to Automations → [Your Welcome Flow] → Activity Log

    • Confirm your test contact entered the Flow

  • Confirm Email #1 arrived within 5 minutes

    • Check inbox (and spam folder just in case)

    • Verify all links work

    • Verify discount code displays correctly

  • Monitor subsequent emails over the next few days

If something doesn't work:

  • Check that your list name in the form matches the list name in the automation trigger (case-sensitive)

  • Verify the automation is toggled to Active

  • Ensure the Drip Sequence itself is Active (not in draft mode)

  • Check Automations → Activity Log for error messages


Quality Tips for High-Converting Welcome Flows

1. Consider Double Opt-In (Region-Dependent)

What it is: After form submission, send a confirmation email requiring the subscriber to click a link to confirm their subscription.

When to use it:

  • Required in EU, UK, Canada (GDPR, CASL compliance)

  • Recommended for all brands to improve list quality and deliverability

How to implement:

  • SendX supports double opt-in natively in form settings

  • Enable "Require email confirmation" in your form configuration

  • The Welcome Drip only starts after confirmation click

2. Craft Effective Preview Text

Why it matters: Preview text appears next to the subject line in inboxes and significantly impacts open rates.

Welcome Email #1 best practices:

  • Subject: "Welcome! Here's your 10% off code 🎉"

  • Preview text: "Thanks for joining [Brand]! Your exclusive discount is inside →"

Avoid these mistakes:

  • "View this email in your browser" (wastes prime real estate)

  • Repeating the subject line verbatim

  • Leaving it blank (email client pulls first body text, usually "Dear...")

3. Set Clear Expectations in Email #1

What subscribers want to know:

  • How often will you email them?

  • What type of content will they receive?

Example opening paragraph:

"Welcome to the [Brand] family! You'll hear from us 2-3 times per week with new arrivals, exclusive deals, and [your unique content].

4. Make the Discount Code Unmissable in Email #1

Design tips:

  • Use a large, bold, colored button or box for the code

  • Make it copyable (not just an image)

  • Repeat the code at the top and bottom of the email

  • Show exactly how to use it: "Enter code WELCOME10 at checkout for 10% off your first order"

Expiration urgency:

  • "Your code expires in 7 days!" (creates urgency without being pushy)


Next Steps: Scale Your Welcome Flow

Once your basic Welcome Flow is running smoothly, consider these enhancements:

Advanced optimizations:

  • A/B test Email #1 subject lines (biggest impact on open rates)

  • Add conditional branching:

    • If clicked discount link → send "Complete your order" reminder

    • If didn't open any emails → send re-engagement message

  • Segment by signup source:

    • Popup subscribers → more aggressive sales approach

    • Blog subscribers → more educational content

  • Personalize by product interest (if your form collects preferences)


Key Takeaways

What you've learned:

  • Welcome Flows convert better than regular campaigns

  • Setup requires two components: form configuration + automation trigger

  • Testing is mandatory before launching to your full list

  • Email #1 is critical: deliver value immediately with clear expectations

  • Preferences links reduce unsubscribes while giving subscribers control

Your action item: Don’t wait for perfection. Launch a simple 2-email Welcome Flow one with a discount code and another sharing your brand story. Even this basic setup consistently outperforms stores without automation.
