Bitrix24 is the ONLY free CRM with email marketing. Most 'free' CRM systems aren't really free – they either limit the number of contacts you can have or how many emails you can send on a monthly basis or so on. The only limits for the free Bitrix24 plan are 12 users and 5GB document storage. Everything else – contacts, deals, quotes, invoices, emails, templates – is unlimited. You even get free email server, if you need it.
If you want to use our built in CRM email integrations via Bitrix24 Marketplace, you can. This gives you bulk mailing, email campaigns, email tracking (open rates, click rates, etc), HTML templates, mail merge and much more.
