Craigslist is one of the most popular advertisement websites in the United States that provides advertisements for services, jobs, housing, local community, and events. It is a powerful market web-based service that helps you sell products, generate traffic, leads, and increase your customer reach.

Providing contact information is essential in Craigslist listings since not all people are replying directly on Craigslist. A great way is to share a link that redirects them to a contact form.

Here’s how you can add your 123FormBuilder online form on Craigslist:

1. Log in to form builder account and open up your form. If you haven’t created it yet, follow this step-by-step guide.

2. After opening the form you wish to share, hover over the Publish section and choose Embed form. Select Text/Image lightbox, make the necessary customizations and copy the code.

Text/Image lightbox

That’s it! Now your listing contains the form, and users can get in touch with you more easily.

First, be sure to check your Spam and Trash boxes. If submissions aren’t there, check if you’ve got the proper form configuration. Here are some tips for having your submission emails behave like regular emails.

In the form builder, go to Emails, and collapse the Show From and Reply-to options section.

Now, select the following variables from the dropdown lists below: your submitter’s name for From name, noreply@123formbuilder.com for From email, and your submitter’s email address for Reply to email.

Notifications settings

Also, create a whitelist in your email settings. This way, you’ll always find your form submissions in your Inbox.

The SMTP feature is available starting from the Gold plan. With this feature, you can send notifications on submissions without the address noreply@123formbuilder.com appearing as the sender in the body of the email.

1. Go to the Emails section of your form and in the left-side panel, under the Deliverability subsection, enable SMTP server. Next, click on Edit SMTP server.

SMTP server

2. In the new lightbox window, insert the Host, Port, Username, Email, and Password of your SMTP server. Select the Protocol your server uses then hit Test connection. You will receive a verification code at the email address specified.

Configure SMTP server

3. Once you have acquired the code, copy and paste it in the verification code box, back in 123FormBuilder. Click on Validate to enable the SMTP connection. From now on, all notification emails will be sent through your SMTP server. More exactly, the sender will no longer be 123FormBuilder, but the email address you have assigned in SMTP Options.

SMTP Validate

Open up the SMTP settings and double-check that the SMTP connection is enabled, under Deliverability section.

This is where you define what links and mentions can be kept from our end on the white label platform, such as documentation or support links. Here, all options are unchecked by default, so the links are available for your sub-users.

White label links

The following 123FormBuilder resources can be disabled and hidden:

Disable Support tab & live chat – unchecked by default. If checked will hide the support tab and chat widget from the interface.

Disable documentation links from the platform – unchecked by default. If checked will disable and hide all links that redirect to 123FormBuilder resources like Knowledge Base articles (for example the “learn more” links from the Publish section or the links from the tooltips that appear when hovering on the “help sign” icons from various sections of the platform). As a future improvement, this option will also hide the “what’s new” section from the Account Menu.

Disable all Publish Form methods that require plugins – unchecked by default. When checked the various publishing means that require 123FormBuilder plugins that can’t be rebranded, such as Shopify, BigCommerce, Facebook, Joomla, WordPress will be hidden.


This is where you can define the links that are available for your sub-users when they access the Help section. By default, all of them redirect to 123FormBuilder resources, but they can all be replaced with custom links or completely hidden. The custom links should include http:// or https://.

White label help section
  • Knowledge Base link – This is set to Default, meaning the 123FormBuilder Knowledge Base is accessible. The other options are Custom, where you can add a different link, and Hidden.
  • Support link – This is set to Default, meaning the 123FormBuilder support form is accessible. The other options are Custom, where you can add a different link, and Hidden.
  • Contact link – This is set to default, meaning the 123FormBuilder Contact Us page is accessible. The other options are Custom, where you can add a different link, and Hidden.
  • Terms of Service link – This is set to Default, meaning the 123FormBuilder Terms of Service page is accessible. The other options are Custom, where you can add your link, and Hidden.

If all links are hidden, then the “Help” section will be completely hidden.

These email instructions apply to the white label version of 123FormBuilder.

The Sender name and Sender email are mandatory and will be applied to all system emails. By default, the name and email associated with your account will be added, but they can be replaced.

White label emails

You have three standard system email templates in the White Label section:

New user created email – this is the email that is sent out when an administrator adds a new user. This email will inform the user of the username and system-generated password that they can change later.

Forgot Password email – this is triggered when users reset their password from the Login page, by clicking on the Forgot Password link.

Reset password email – This is triggered when admins reset the password of a user from the Users section.


Customizing the Email templates

All email templates have defaults for subject and body, but they can be edited. Clicking on the templates table will trigger a small pop-up where the emails can be edited either as plain text or HTML. If you are not happy with the customization, you can always reset the template to default.

Email template

The subject line can be empty, but it’s recommended to include a subject, to avoid emails going into spam.

The email body can’t be empty. The custom variables, which will be replaced with relevant content when the emails are sent, can be included from the plus symbol next to the Body type dropdown. Images can be added to the body, but only via links.

Email body

All changes made on the White Label customization page will be saved and applied for your sub-users when they log in through the custom domain only after the Apply Changes button is clicked. If the page has errors (e.g. required fields are left empty or pasted links don’t have the required format) the changes can’t be saved. Clicking on the Revert button will cancel all unsaved changes.

123FormBuilder offers a white label form building package for companies that wish to integrate form building capabilities into their system.

By white labeling 123FormBuilder, you will be able to fully customize your 123FormBuilder backend and provide your own form building service to any number of sub-users you need.

The White Label solution provides our platform as a blank canvas for you to customize.

The domain, style, and platform text customization are done from the White Label Forms panel from the My Account menu.

The My Account menu is accessible by clicking on your username.

While Label customization

Domain alias

You need to add a custom domain, which will replace the 123FormBuilder domain and direct users to the Welcome page of the White Label solution. This step is mandatory.

The setup of the domain is done with the assistance of one of our consultants, as we will need to change a few things in our server configuration. We will then provide you with the endpoints that you should include in your server DNS.

Domain alias

You can customize the logo that will show up on the Welcome page, Login page, and across the platform by replacing the default 123FormBuilder logo with your own. When clicking on the default 123FormBuilder logo, an interface will pop up that will allow you to upload your own logo directly on the platform. If you don’t upload a custom logo, then the default 123FormBuilder logo will be applied.

Accepted formats for the logo image are PNG, JPG, TIF, GIF. The max image size allowed is 1024 x 256px. The max file size is 2MB. For best results, the logo width should be bigger than the height and white logos should be avoided, as they will not be visible inside the platform and the related pages.


Favicon

Customizing the favicon is optional. We include a default one, which, when removed, will leave the favicon blank, until you upload your own.

Accepted formats are PNG, JPG, ICO, GIF. The max image size is 32 x 32px. The max file size is 500kb. You can upload image files directly from your device. The Favicon applied in Account Details will not work if the White Label Form functionality is enabled.

Collecting money via forms is an easy and fast way to grow your business. Our form builder provides a very simple way to receive payments with your forms through multiple payment processors. You will be able to accept donations, orders, and subscription fees easy as 1-2-3. Offline payment suggests that money is transferred at a later date. With an offline payment as a method, form users can pay by check, invoice, on-site or other options.

Both online and offline payments are important to consider when creating an order or registration form.

When you enable the payment integration, the form automatically redirects to the payment page. Form rules can redirect users to another webpage based on the user’s input. Form rules will have priority over the redirect to the payment summary page.

First, you need to establish the condition when to redirect to that webpage URL.

Open your Form Editor and add a choice field. In our example, we labeled it Payment Method and listed two options: Pay Online and Pay by Check. To ensure that the user checks one of them we mark the field as required.

payment method

At this point, even if a user chooses either of those options, the redirect will still be made to the payment page.

Navigate to Rules and switch to the Form Rules tab.

Form Rules

Create a new rule, like the following:

If Pay by Check is checked

Then redirect to ______ (paste your webpage URL)

Each time Pay by Check is selected, the redirect to your webpage is made. When Pay Online is checked, the redirect will be made to the payment summary page.

That’s it! Now you have a form with both online and offline payment options.

123FormBuilder protects the data entered on any form. We do our best to track down and ban all the forms created by users of our service for data phishing purposes. That message appears on any free form to avoid phishing attempts and scammers. Phishing is a type of online fraud that can result in identity theft.

It is forbidden to create forms that request sensitive data, such as passwords, email credentials, or other credentials, from form users. Keep your passwords, financials, and other personal information safe and protected.

For order forms, we offer several user-friendly payment processors.

We don’t allow form owners to use another entity’s brand, title, logo, or name in a manner that may result in misleading form users.

We do not allow our services to be used for activities related to or promoting racism, pornography, segregation, religious hatred, or any illegal activities. We suspend and ban any kind of form that is violating our terms of service.

If you ever receive a form that is asking you to provide your personal information, such as your social security number, password, or account numbers, do not submit it. If you stumbled upon a form that seems suspicious, please contact us to take action against it.
