This sounds surprising, but stop putting your email address on your website. Here's why.
One: the spam
The moment your email is on a public page, bots scrape it. There are countless services crawling the web harvesting addresses, and you'll start drowning in promotional emails you never asked for. To them, you're just an item on a list.
Two: use a contact form instead
So how do people reach you? A contact form. Name, their email, the message, they fill it in and it lands in your inbox instantly. You still get the message, they don't have to log into their own email account, and you don't get the spam. Everyone's happy.
Three: it filters the riffraff
Here's the part people miss. A form filters out the time-wasters. There are people who are just curious, who want to ask your price with no intention of buying. They won't bother filling in a form. The serious ones will.
If you put a phone number up, people call you out of pure convenience, asking your price or your opening hours. A form makes them pause and answer a few questions first.
And those questions do double duty. Build in the things you'd have to ask anyway. If you rent out function rooms: how many people, what date, what's the occasion. Now your enquiries arrive already qualified.
The takeaway
A well-built contact form might be the best feature you ever add to your website. Less spam, fewer time-wasters, better enquiries.
