How to fill your CRM with Spanish B2B leads without buying a huge database
Why buying 20,000 records to work 300 is wasted money, and a method to build a quality prospect list of Spanish companies by province and size, paying only for what you use.

Entering the Spanish market, many companies buy a database of thousands of records. The team works it enthusiastically for two weeks; by week three nobody opens it. Half the numbers don't answer, the emails bounce and the ones that reply have nothing to do with your ideal customer.
The problem isn't quantity. It's that the list wasn't built for you.
Start from the end
If you want 5 new Spanish clients a month and close one in four proposals, you need 20 proposals. If one in five conversations becomes a proposal, that's 100 conversations; if you reach one in two companies, 200 companies a month. Two hundred, not twenty thousand.
Three filters
- Where: Spanish province(s). If you deliver in person, stay local.
- Size: a sole trader is not a 40-person company. Headcount changes budget, decision-maker and sales cycle.
- Activity: workshops, clinics, restaurants, hauliers…
On IberiaData you filter by province, headcount band and whether the profile has email, phone or both.
Pay only for what you work
| Pack | Price | Approx. full profiles | Cost per profile |
|---|---|---|---|
| Starter | €9.90 | 8 | €1.19 |
| Professional | €49.90 | 55 | €0.91 |
| Business | €199.90 | 333 | €0.60 |
And if a profile has no phone, you don't pay for it.
Quality over quantity
- The company's contact, not its accountant's. The classic flaw in Spanish SME databases.
- Mobiles. In small businesses the landline reaches an employee; the mobile reaches the owner.
- Emails that exist. A domain with no mail server is a guaranteed bounce.
Add context to the CRM
Don't import just name and number: add province, size and why the company is on your list. For volume, the API sends the data straight to your CRM.
Measure
Each month: companies contacted, conversations, proposals, clients. Adjust filters with the numbers. In three months you'll have a predictable pipeline.
Frequently asked questions
How many leads do I need per month?+
Work backwards from your conversion rate. If you close 1 in 20 companies you contact and want 5 clients a month, you need about 100 well-chosen companies, not 10,000.
How do I import contacts into my CRM?+
Export to CSV from your IberiaData account or use the API to send them straight to HubSpot, Pipedrive, Zoho or Clay.
