Excel or CRM: when a spreadsheet for leads is not enough
Many small businesses keep leads in Excel or Google Sheets, appointments in Calendly or Reservio, and e-mails in Ecomail or SmartEmailing. That works at the start. LeedFox puts those steps in one place: every lead from an ad or your website gets an SMS and an e-mail right away, the customer picks a time, and everything shows up on one card.
The LeedFox team wrote this comparison, so we are one of the sides being compared. Facts about the other tools come from their own websites as of Nov 9, 2026, with the source on every row. If you spot a mistake, write to us and we will fix it.

When Excel + Reservio + Ecomail makes sense
- You get a few leads a week and can handle them yourself.
- A free plan from Calendly or Reservio covers your bookings.
- You send e-mails mostly as a newsletter, not as a reply to a new lead.
- You don't want to pay for a new tool until you know leads are slipping away.
When LeedFox makes sense
- Leads come from Facebook and Instagram ads and you copy them into the spreadsheet by hand.
- You want every new lead to get an SMS and an e-mail right away, even when you're away from your desk.
- You need to see messages, appointments and the deal stage for one customer in one place.
- Several people handle leads and you want to know who contacted whom.
A spreadsheet with add-on tools is a sensible start. You probably already have Excel or Google Sheets, Calendly and Reservio both have free booking plans, and Ecomail sends up to 200 e-mails a month for free, including behavior-based automation. For one person with a few leads a week, it is cheap and easy to follow.
The trouble starts when leads pick up. Each tool lives on its own: the spreadsheet does not know the customer booked a time, and the e-mail tool does not know a lead just came in from an ad. A Facebook lead gets into the spreadsheet by manual export or through Zapier or Make, and an instant SMS does not go out without extra work. SmartEmailing's price list did not load for us, so we do not list its price.
LeedFox handles these steps in one place: it takes the lead from an ad or a form, sends an SMS and an e-mail, offers a time slot and stops reminders when the customer replies. If your spreadsheet works for you, keep it. If leads are slipping through because of it, it is time for a CRM.
What people ask
When is Excel no longer enough for leads?
When leads come in from ads faster than you can copy them over, when more than one person answers them, or when you lose track of who you have already contacted. Until then, a spreadsheet with booking and e-mail tools is usually enough.
Is LeedFox more expensive than Excel with add-ons?
A spreadsheet with the free plans of Calendly, Reservio and Ecomail can cost nothing. According to their price lists, paid Calendly plans start at $10 per user per month billed annually, and Reservio and Ecomail price their paid plans in Czech crowns. SMS is paid separately. As for LeedFox, it depends on what you will use. We go through it on the demo.
Can I import my spreadsheet into LeedFox?
Yes. Save the spreadsheet as CSV and import it into LeedFox. On the demo we go through which columns to bring over and how to set up stages.
Where is a spreadsheet with add-ons stronger?
It is cheap to start, everyone knows how to use it, and Reservio and Ecomail are mature tools with free plans. Reservio also has a mobile app. If nothing is slipping through, you do not need to change anything.
Where is the data stored?
LeedFox keeps its database in the EU, in Frankfurt. With a spreadsheet and add-ons, the data sits with each tool separately. We did not check where.
