Registration email link not being sent I'm using the following form, and occasionally through testing the e-mail activation link will send, however the majority of time it never gets sent. Did I do something wrong with the form?

&lt;form method="post" accept-charset="UTF-8"&gt;
        {{ getCsrfInput() }}
        &lt;input type="hidden" name="action" value="users/saveUser"&gt;
        &lt;input type="hidden" name="redirect" value="/success/"&gt;

        {% macro errorList(errors) %}
            {% if errors %}
                &lt;ul class="errors"&gt;
                    {% for error in errors %}
                        &lt;li&gt;{{ error }}&lt;/li&gt;
                    {% endfor %}
                &lt;/ul&gt;
            {% endif %}
        {% endmacro %}

        {% from _self import errorList %}

        &lt;h3&gt;&lt;label for="username"&gt;Username&lt;/label&gt;&lt;/h3&gt;
        &lt;input id="username" type="text" name="username"
            {%- if account is defined %} value="{{ account.username }}"{% endif -%}&gt;

        {% if account is defined %}
            {{ errorList(account.getErrors('username')) }}
        {% endif %}

        &lt;h3&gt;&lt;label for="email"&gt;Email&lt;/label&gt;&lt;/h3&gt;
        &lt;input id="email" type="text" name="email"
            {%- if account is defined %} value="{{ account.email }}"{% endif %}&gt;

        {% if account is defined %}
            {{ errorList(account.getErrors('email')) }}
        {% endif %}

        &lt;h3&gt;&lt;label for="password"&gt;Password&lt;/label&gt;&lt;/h3&gt;
        &lt;input id="password" type="password" name="password"&gt;

        {% if account is defined %}
            {{ errorList(account.getErrors('password')) }}
        {% endif %}

        &lt;input type="submit" value="Register"&gt;
    &lt;/form&gt;
If you're using phpmail or sendmail under Settings->Email in the control panel, they are notoriously unreliable at delivering emails consistently.

Try using a proper SMTP relay or a transactional email provider like Mandrill.
