How Can Smartlead Variables Boost Personalization in Your Cold Email Campaigns?

Explore Smartlead’s custom variables to supercharge your email personalization and create targeted campaigns that stand out in crowded inboxes.

Smartlead provides a range of personalization variables that make your emails feel more tailored, timely, and human. By utilizing these custom variables, you can increase engagement and response rates.

Let’s break them down with examples and usage tips.

1. Time-Based Personalization

Make your emails feel current and context-aware with time-based greetings.

a) Time of Day

Use: Good {{sl_time_of_day}}

This variable adjusts based on the campaign timezone and the time of send.

• Before 12 PM → “Good morning”

• 12 PM – 3 PM → “Good afternoon”

• After 3 PM → “Good evening”

Example: “Good {{sl_time_of_day}}, John” → “Good afternoon, John”

✅ Always review your email before sending to check if the variable is rendering correctly.

b) Day of the Week

Use: Happy {{sl_day_of_week}}

This converts to the actual day name when the email is sent.

Example: “Happy {{sl_day_of_week}}” → “Happy Friday”

⚠ Make sure there are no spaces inside the brackets.

2. Dynamic Date Personalization

You can also use Smartlead to insert dynamic dates into your copy for booking meetings, reminders, or follow-ups.

a) Relative Dates with Custom Format

Use format:
{{sl_date "timeframe" "format"}}

Examples:

• {{sl_date "10 minutes from now" "dddd, MMMM Do YYYY"}} → Thursday, January 19th 2023

• {{sl_date "2 days from now" "MMMM Do YYYY"}} → January 21st 2023

Result:

b) Common Use Cases

1. Add 2 days from now:
   {{sl_date "2Days"}} → 21 Jan 2023

2. Subtract 2 days:
   {{sl_date "2Days ago"}} → 17 Jan 2023

3. Add 2 days with custom format:
   {{sl_date "2Days" "Do MMM"}} → 21st Jan

4. Add 2 weeks from now:
   {{sl_date "2week"}} → 02 Feb 2023

5. Add 2 months from now:
   {{sl_date "2month"}} → 19 Mar 2023

6. Add 2 years from now:
   {{sl_date "2year"}} → 19 Jan 2025

c) Weekday-Only Dates

To avoid weekends, use:

{{sl_date "now_wd 2Days" "Do MMM"}}

Here, now_wd skips weekends in the calculation.

3. Sender & Signature Variables

Add dynamic sender and signature elements without manually typing them.

Use these variables when you want full control over the placement of sender information in your email.

Final Tips

• Always preview your emails before sending.

• Ensure no formatting errors (like spaces inside variable tags).

• Mix multiple variables for a human touch, but avoid overdoing it.

By combining these variables, you can create personal, timely cold emails that feel intentional without manual effort.
