Environment variables and configuration done properly
A missing environment variable should crash the app at startup, not produce a confusing bug three hours into production.
Most broken contact forms are not broken at all — the emails are going to spam, or to an address nobody checks. Test yours by submitting a real enquiry from your phone, then check your inbox, your spam folder, and any shared inbox it might route to. If nothing arrives, the sending configuration is usually the cause.
Submit a real enquiry from your phone on mobile data, then check every inbox it could reach.
| Cause | How common | Fix |
|---|---|---|
| Emails going to spam | Very common | Email authentication records |
| Sending to an old address | Common | Update the form's destination |
| Email password changed | Common | Update the sending credentials |
| Form plugin broke on update | Common on WordPress | Reconfigure or replace |
| Spam protection blocking real people | Occasional | Adjust the settings |
| Form never configured at launch | Occasional | Configure it |
Most contact forms send the email 'from' the visitor's address, through your website's server. To a spam filter that looks like forgery, because the server sending it is not authorised to send on that person's behalf.
You often would not, which is what makes this so damaging. If enquiries dropped suddenly with no other explanation, test the form first before assuming it is a marketing problem.
A form usually converts better and gives you structured information. Show your email and phone as well, since some people prefer them and it is a fallback if the form fails.
Yes, but keep it light. Aggressive protection blocks real customers, and a hidden field that catches bots is usually enough without making people solve puzzles.
Yes, most form tools can send a text notification. For urgent trades where speed wins the job, it is genuinely worth setting up.

Work through these seven checks in order. One of them is almost always the answer.
They do different jobs. The risk is building only on land you do not own.
No spam. Just the occasional case study and craft breakdown.
