Can anyone suggest a free service I can use to store all my business contacts? Am currently using Excel spreadsheets but would like to start using a proper database system - something that is free for under 1000 or 2000 contacts. I am soon to launch a smartphone app for tech startups and have been collecting expressions of interest and email addresses via several forms. All this contact information has been directed and stored in Excel spreadsheets. I now have up to 1000 user contact profiles, spread over several different user and customer groups and would like to put these into a database. Quite soon I plan to use MailChimp to broadcast when the service/app goes live and would like to send out a slightly different message to each group of users or customers. From my research I can't work out if I need a CRM system, or a Contacts database. I have looked at: ZohoCRM, Zoho Contacts, Odoo and can't decide what I need. Here are my requirements as I see them ... • Ability to assign a contact or user to a group (or sub-group) name of my choosing, like this ... 1 Founder / Start-up: 2 Promotion Targets: - Tech Blogs - VC Blogs - Business News Sites (Top Tier) - Business News Sites (Low Tier) - Business Networks - App Reviews & Directories 3 B2B Targets: - Accelerators - Incubators & Biz Education - Deal Matching & Brokers - Crowdfunders - VC Firms - Angel Investors 4 Suppliers: - PR, Press & Journalists - Sponsors 5 - Other: • The service must be free at least to 1000 contacts • Helpful if it integrates with MailChimp All suggestions would be gratefully received.
