What is in this greenhouse email list?

The file lists 608 Google Maps businesses in the Greenhouse category, counted on 9 November 2026. A row is a growing operation or a garden retailer that works under glass or plastic: a family greenhouse that sells bedding plants and hanging baskets in spring, a wholesale grower that supplies garden centers, a vegetable and herb starter farm, or a farm stand with a greenhouse attached. One operation at one listing is one row.

426 rows have an email address from the grower's own site, one per business. Phone numbers appear on 565 rows and websites on 436. Many greenhouses are seasonal and sell on a sign by the road, so a good share of rows carry a phone number and no site.

All the rows share the Google category Greenhouse.

How can you segment the file?

You open the CSV in Excel or Google Sheets and filter on its columns. Because the category is the same everywhere, you segment by location, name and address type.

The state and city columns line up with growing regions. Pennsylvania, Ohio, Michigan and New York hold the largest groups, and Michigan has a cluster around Grand Rapids. A seller of potting soil or plug trays can pick a region that is a day's drive from its warehouse.

The name column hints at what a greenhouse does. Names with farms, nursery, garden center or plants point to retail or wholesale growing. Names with orchids, ferns, succulents, tropicals or herbs point to a specialty crop. Names with hydroponic, produce or microgreens suggest food production. Names with a family surname and the word greenhouses are often a seasonal retail grower. The website, where there is one, tells you which it is.

• State and city: a growing region within delivery range.
• Name keywords: nursery, garden center, orchids, hydroponic, produce.
• Email type: three equal groups of 142, namely role, named person and free mail.
• Website: read the plant list, the wholesale page and the season dates.

Who buys a greenhouse email list?

The buyers sell to growers. Seed and plug producers sell young plants and flower, herb and vegetable seed. Potting mix, peat and perlite suppliers pitch growing media. Fertilizer, pesticide and biological control companies sell crop protection. Makers of pots, trays, hanging baskets, plant tags and labels pitch containers. Heating, shade cloth, film and glazing suppliers sell structures and repair materials.

Others sell farm services: irrigation and fertigation system vendors, LED grow light makers, greenhouse builders, boiler and propane suppliers, delivery truck and cart makers, point of sale and wholesale order software and crop insurance agents.

How do you run outreach to greenhouses?

Begin with the address groups. The file has 142 role addresses such as info@ or sales@, 142 named-person addresses and 142 on free mail domains. A seasonal greenhouse is usually run by a family, and a named or free mail address is likely to reach the grower who makes the buying decisions. A role address may be read by a retail counter person in season and by nobody in winter.

Timing decides whether the note gets read. In the northern states, the busiest weeks run from late March to early June, and owners are in the greenhouse all day. Order planning for the next season happens in autumn and winter, when the greenhouse is quiet. Write between November and February, and put the product, the price per flat or per case and the order deadline in the first lines.

Match the offer to the crop and the scale. A plug producer should list varieties and tray sizes. A pot supplier should state the minimum order and the lead time. A grow light vendor should talk about the electricity cost per square foot. A greenhouse that sells vegetable starts needs a different pitch from a wholesale grower of poinsettias.

Because many greenhouses answer mail slowly, a phone call after the email is natural, and the phone column is filled on most rows. Send small batches and remove any address that fails.

What email rules apply when you contact growers?

Two points under CAN-SPAM apply to a commercial email to a grower: put your valid postal address in the message, and give a working opt-out that you honor. A grower who replies to stop should be removed before your next mailing.

Which states and cities should you start with?

Pennsylvania has 68 listings and 48 emails, and Ohio 65 and 46. Michigan has 50 and 35, New York 49 and 34, Wisconsin 36 and 25, Indiana 32 and 22, Illinois 25 and 18, and Minnesota and Missouri 21 and 15 each. Texas has 20 and 14.

The city counts are small. Grand Rapids has 10 listings, Indianapolis 7 and St. Louis 6. Cincinnati has 5, and Hudsonville, Toledo and Cleveland 4 each. Anchorage, Jacksonville and Jamesport have 3 each.

A supplier of plugs or pots can work through the Great Lakes states one after another, since the shipping distances are short and the season is similar. A seller of a grow light system can pick Michigan and Ohio first for the larger greenhouse count and then move west.
