Form Builder With Auto Email Response for Clients: Why It’s Worth Turning On

What an auto email response actually does

The moment a person submits your form, the form builder can send them an email automatically. You write the message once in the form settings—something like “Thanks for getting in touch. We’ll reply within 24 hours.” or “We’ve received your enquiry and a team member will call you by tomorrow.”—and from then on every submitter gets that email. No one has to remember to hit “send” manually. It’s instant, consistent, and runs in the background. That’s what we mean by a form builder with auto email response for clients: the client here is the person who filled the form (your prospect or customer). They get a reply in their inbox within seconds. You look organised and attentive even if you’re busy and will only get to the lead in a few hours.

It’s different from the notification email you get. You get an email that says “New form submission from John, phone 98xxx.” That’s for you. The auto response is for them. So you have two emails in play: one to you (so you can follow up) and one to the submitter (so they know they’ve been heard). Many form builders support both. You turn on “Notify me” and “Send auto-reply to submitter” and you’re set.

Why it matters for you and for them

For the person who submitted: they don’t have to wonder if the form worked. They get a confirmation right away. That reduces “Did you get my message?” emails and calls. It also sets expectations: “We’ll get back in 24 hours” means they know when to expect a reply and are less likely to chase you or go to a competitor in the meantime. For you: you look professional. Instant confirmation is something people expect from big brands; doing it for your small business or agency makes you stand out. And because you’ve already told them when you’ll respond, you’re under less pressure to reply in the next five minutes—you’ve bought yourself time while still seeming responsive.

What to put in the auto-reply message

Keep it short. Thank them, confirm you received their submission, and say what happens next. For example: “Hi, thanks for reaching out. We’ve received your details and will get back to you within 24 hours. If it’s urgent, call us on [number].” You can add your logo or branding if the form builder allows. Avoid long paragraphs or multiple links—they might trigger spam filters. A simple, plain or lightly formatted email works best. If you have different forms (e.g. “Request a demo” vs “General enquiry”), you can often set a different auto-reply per form. The demo form might say “We’ll call you to fix a slot within 4 hours”; the general enquiry might say “We’ll reply by email within 1 business day.” Match the message to the form so the promise is accurate.

When to use it (and when to skip)

Use auto email response for any form where a human will follow up later: contact forms, enquiry forms, demo requests, lead capture forms. The submitter expects a reply; telling them “we got it and we’ll be in touch” is helpful. You can skip it for forms where the outcome is immediate—e.g. a form that, on submit, shows a thank-you page with a download link or a confirmation number. In that case the page itself is the confirmation. But for “we’ll call you” or “we’ll email you back,” the auto-reply is a good idea.

What to check in your form builder

Not every form builder has auto-reply. When you’re choosing a form builder with auto email response for clients, look for a setting like “Send confirmation email to submitter” or “Auto-reply message.” You should be able to type or paste the message and optionally use a placeholder for their name (e.g. "Hi {{name}},"). Some tools let you set a subject line too, e.g. “We received your enquiry.” Check whether the free plan includes it; a few limit auto-replies or charge per email. For typical contact or lead forms, a few dozen auto-replies per month is normal, so the plan should allow that. LeadFormHub lets you configure an auto-reply so submitters get an instant confirmation; you set the message in the form settings. See our features and pricing for how it works with notifications and lead capture.

Deliverability and spam

Auto-replies are sent from the form builder’s email system. They usually land in the inbox, but sometimes they can go to spam if the content looks generic or the sender is unknown. To improve deliverability, keep the message natural and avoid spammy words (“FREE,” “Act now,” etc.). If your form builder lets you use your own “From” name or domain, that can help. For most small businesses, the default setup is fine—just check your own form once by submitting a test and seeing where the email lands.

Quick recap

A form builder with auto email response for clients sends an instant confirmation to everyone who submits. You write the message once; they get “We got it, we’ll reply by X.” That sets expectations, reduces follow-up anxiety, and makes you look professional. Use it for contact, enquiry, and lead forms where you’ll respond later. Keep the message short and accurate. Turn it on in your form settings and you’re done.

Frequently asked questions

Is auto-reply the same as the notification I get?

No. The notification email goes to you (or your team) with the submission details. The auto-reply goes to the person who filled the form, confirming you received their message. You need both for a complete flow: you get the lead, they get the confirmation.

Can I customise the auto-reply per form?

In many form builders, yes. Each form can have its own auto-reply message and subject. So a “Demo request” form can say “We’ll call you to fix a slot,” and a “Contact” form can say “We’ll reply within 24 hours.”

Will auto-reply emails go to spam?

They can occasionally. To reduce that, keep the message simple and avoid spam trigger words. If your tool allows, use your brand name in the “From” field. Test by submitting the form yourself and checking inbox vs spam.
