What is Dynamic Email Content? – AWeber Knowledge Base

Dynamic email content allows you to tailor your email messages to the interests of each subscriber. There are a lot of different variables that you can pull into your messages, like subscribers' geographic location and their personal information. Content that is more relevant to subscribers often translates into increased engagement in terms of opens, clicks, and conversions.

Where can I use dynamic email content?

You can make use of dynamic email content anywhere in the AWeber message editor, including the subject line.

How do I write dynamic email logic?

In order to code for dynamic email content in your messages, you would have to include the logic tags below.

{{ ... }}	Print the value of a subscriber variable	Hello {{ subscriber.name }}
{% ... %}	Evaluate an expression	{% if subscriber.signup.city == 'Philadelphia' %} Local deals in Philly! {% endif %}
{# ... #}	Write comments in your message that are not seen by your subscribers.	{# This is a hidden comment. #}
{% raw %}	Markup within the raw tag will not be evaluated as a variable or statement.	Here is how I personalize my email greeting: {% raw %} Hello {{ subscriber.first_name }}. {% endraw %}

Operators

Operators help you display specific content if certain conditions are met. If the first condition outlined by the "if" operator is not met, then the system will look to another condition based on the "elif" operator. If neither condition is met, then the system will look to the content with the "else" operator.

Display message content IF the statement is true.

{% if subscriber.custom_field['pet'] == 'dog' %} 
    Save 20% dog food!
{% endif %}

elif

If the first condition isn't met, evaluate another condition.

{% if subscriber.custom_field['pet'] == 'dog' %}
    Save on dog food! 
{% elif subscriber.custom_field['pet'] == 'cat' %}
    Save on cat food!
{% endif %}

else

Display the following content to subscribers that did not meet any of the conditions above.

{% if subscriber.custom_field['pet'] == 'dog' %}
    Save on dog food! 
{% elif subscriber.custom_field['pet'] == 'cat' %}
    Save on cat food!
{% else %}
    Save on pet food!
{% endif %}

Comparison Operators

Comparison operators work in conjunction with the operators above.

==	equal to
!=	not equal to
>	greater than
>=	greater than or equal to
<	less than
<=	less than or equal to

Filters

Filters help you customize the content by capitalizing specific letters, displaying fallback content when the subscriber doesn't have a value, and displaying a random option from a set of choices.

upper()	Converts each character in a string to uppercase	{{ "hello there" \| upper() }} HELLO THERE
lower()	Converts each character in a string to lowercase	{{ "HELLO THERE" \| lower() }} hello there
capitalize()	Capitalizes the first word in a string	{{ "hello there" \| capitalize() }} Hello there
title()	Capitalizes each word in a string	{{ "hello there" \| title() }} Hello There
default()	Provides a fallback if the variable has no value assigned	Dear {{ subscriber.first_name or "friend" }}, Dear friend,
truncate()	Returns a truncated version of a string	{{ "The quick brown fox jumps over the lazy dog" \| truncate(20) }} The quick brown fox...
replace()	Return a copy of a string with all the occurances of a substring replaced with a new one.	{{ "The quick brown fox jumps over the lazy dog" \| replace("fox", "rabbit") }} The quick brown rabbit jumps over the lazy dog
first()	Returns the first item of a sequence	{{ ['Apples', 'Oranges', 'Grapes'] \| first() }} Apples
last()	Returns the last item of a sequence	{{ ['Apples', 'Oranges', 'Grapes'] \| last() }} Grapes
unique()	Returns a unique set of items in a sequence	{% set colors = ['red', 'blue', 'red', 'orange', 'blue', 'white'] %} {% for item in colors \| unique() %} {{ item }} {% endfor %} red blue yellow orange white
count()	Returns the number of items in a list	{{ ['a','b','c','d','e','f'] \| count() }} 6
sum()	Returns the sum of a sequence	{{ [12, 4, 545, 714, 332, 451, 975, 8, 1, 34, 342] \| sum() }} 3418
min()	Returns the smallest item in a list	{{ [12, 4, 545, 714, 332, 451, 975, 8, 1, 34, 342] \| min() }} 1
max()	Returns the largest item in a list	{{ [12, 4, 545, 714, 332, 451, 975, 8, 1, 34, 342] \| max() }} 975
random()	Select a random item from a set of choices	{{ ['Apples', 'Oranges', 'Grapes'] \| random() }} Grapes
join()	Returns a string of items joined by a separator.	{{ ['Apples', 'Oranges', 'Grapes'] \| join(" \| ") }} Apples \| Oranges \| Grapes
select()	Filter a sequence to items matching the criteria provided.	{% for number in [1, 2, 3, 4, 5, 6, 7] \| select("odd") %} {{ number }} {% endfor %} 1 3 5 7 Other examples include: {{ numbers \| select("odd") }} {{ numbers \| select("even") }} {{ numbers \| select("divisibleby", 3) }} {{ numbers \| select("lessthan", 42) }} {{ strings \| select("equalto", "mystring") }}
random_number()	Returns a random number between two values.	{{ random_number(1,500 }} 371
round()	Round a number to a given number of decimal places	{{ 34.2374 \| round(2) }} 34.24
