Pricing Zoho Campaigns

Pricing Zoho Campaigns

HI, I'm planning to use Zoho Campaigns for another company. This company has a  database of 17000 subscribers. What would be the best option for me ? 

Can you sum up how much would that cost me  to monthy send a newsletter to these subscribers ? 

1) If I choose Zoho CRM Plus 
2) If I only choose Zoho Campaigns `

Thanks in advance,
