Send4 – AI SMS Lead Follow-up for Contact Forms

FAQ

How do I text a lead as soon as they submit a contact form?

Connect the plugin to Send4, then go to Send4 → Forms & Triggers, pick the form, choose the field that holds the
phone number and turn the form on. In Send4, a flow with a WordPress form trigger texts each new lead within
seconds. The steps are the same for Contact Form 7, WPForms, Gravity Forms and Elementor Pro.

Do I need a phone number field?

Yes. Send4 follows up by SMS, so a submission with no phone number has nobody to reach. The plugin refuses
to enable a form until you tell it which field holds the number.

A form sends, but nobody is texted. Why?

Open Send4 → Dashboard. When your Send4 account cannot text anyone yet, a card at the top, “Before Send4 can text
your leads”, lists each missing step: an active plan, a flow listening for your forms, the phone number Send4 texts
from, and the account that number sends through. Each step links to the page in Send4 that fixes it. The submissions
themselves are not lost: Send4 has them.

Which number are my leads texted from?

One you connect in Send4. Send4 sends through your own Twilio or Vonage account: add the account’s keys under
Settings → Integrations → Provider credentials in Send4, add the phone number under Settings → Phones, and
put the reply addresses Send4 shows you into your Twilio or Vonage console so that answers come back. The account, the
number and what they cost are yours, and so are the rules your country sets for business texting, such as 10DLC
registration in the United States.

If your leads are in Lithuania, Send4 can provide the number instead: ask us to add one to your account. It texts
Lithuanian numbers only.

What happens to fields I do not map?

They are all sent as context, keyed by their label, and Send4 gives them to the AI so it can answer
questions about what the person actually asked for. Nothing is dropped.

Does the visitor wait for Send4?

No longer than three seconds. If Send4 does not answer within that, the submission goes into a local retry
queue and the visitor sees their normal confirmation immediately.

What if Send4 is down?

The submission is stored in a table in your database and retried on a backoff — after a minute, five
minutes, fifteen, an hour, then every six hours for about a day and a half. Retries reuse the same
submission identifier, so a lead cannot be delivered twice.

Which form plugins does it work with?

Contact Form 7, WPForms (including Lite), Gravity Forms and Elementor Pro are supported today. Each one is
a small adapter class; ask us and we will add yours.

Why would a form refuse a phone number?

Only if you turned on Refuse a submission whose phone number has no country code for that form (it is off
by default). Send4 texts the lead, and a text needs the full international number: +44 20 7946 0958, not
020 7946 0958. The plugin never guesses a country code for a number that has none — it asks the visitor to
add one instead, with the message “Please enter your phone number with its country code, starting with + —
otherwise we cannot text you back.”

The check is deliberately loose: a leading + (or 00) and a real country code, 7 to 15 digits. It does not
second-guess the length of a number inside a country. An empty, optional phone field is never refused.

Every refusal is written to the activity log on the Send4 dashboard with the form, the reason and the shape of
what was typed — the first two or three digits and how many there were, as in 86••••••• (9 digits) — but never
the number itself. That is enough to see that visitors are typing the national format, and not enough to call
one of them. The dashboard also counts refusals per form. To see which forms check, run wp send4 forms and read the validates column.

Developers can change the message with the send4_phone_error_message filter, and add a country calling code
with send4_phone_calling_codes.

What does the country picker do?

With Add a country picker to the phone field on, the visitor chooses a country from a searchable list, the
number is formatted as they type, and it is sent to your form plugin as +37060012345. It is added to the field
you mapped as the phone number, whatever kind of field that is — you do not need to rebuild your form.

It loads only on pages that show a form with the picker on. If you use a page cache, clear it after changing
the setting.

On Gravity Forms, set the phone field’s format to International. The “Standard” format only accepts
North American numbers written (###) ###-#### and would refuse the number the picker sends, so a field in
that format gets no picker and no country-code check. The form’s Send4 settings say so when that is the case.

What about visitors with JavaScript turned off?

They see your form exactly as before, with no picker. If the form refuses numbers without a country code, the
check still runs when they submit, so they will be asked to type the + and country code themselves. Nothing
is lost: they can fix it and send the form again.

The picker does not appear in my Elementor popup

A popup Elementor loads after the page has loaded, over AJAX, is the one case the plugin cannot see — Elementor
decides what that response contains. The check on submission still works; only the picker is missing. Declare
the form yourself, with the popup’s form widget id (the data-id on the widget) and the phone field’s ID:

add_filter( 'send4_phone_targets', function ( $targets ) {
    $targets[] = array(
        'scope'    => '[data-id="a1b2c3d"]',
        'input'    => '[name="form_fields[phone]"]',
        'validate' => true,
    );
    return $targets;
} );

I use WPForms Pro’s Smart phone field. Will I get two pickers?

No. If a field already has a picker, Send4 leaves it alone, and the check on submission still applies.

Does it phone home if I do not configure it?

No. Until you start connecting the site, the plugin makes no outbound requests at all.
