01
WhatsApp on the same API
Resend, SendGrid, Mailgun, Postmark, and Unosend are email-only. Zindua sends WhatsApp notifications from the same POST /api/v1/send. OTP is one template on Line 1.

Zindua vs the rest.
One API. Your providers.
Pricing and features side by side so you can choose wisely. Zindua is not another hosted ESP. Email, WhatsApp, and PushMirror on one route. Figures from public pages. Verify before you buy.
WhatsApp campaigns stay on the dashboard desk. OTP is a template on Line 1.
Not an ESP
Zindua does not replace Resend, SendGrid, Mailgun, Postmark, or Unosend.
Those products operate or broker mail delivery. You verify a domain on their platform, they send from their infrastructure, and you pay them for volume. Zindua does not replace that layer.
You connect Gmail, Outlook, SendGrid, Mailgun, SES, or your SMTP, plus your own WhatsApp number. We give you templates, one REST route, logs, and a DNS helper on Pro, not a global SMTP farm or warmed IP pool.
Need fully managed deliverability with no provider account? Use an ESP from the tables. Want one API for email, WhatsApp, and push on accounts you already have? Use Zindua.
Why Zindua
Five things the table does not shout.
02
Free includes WhatsApp
Free: connect your number, scan QR, send 100 WhatsApp notifications/mo plus 8,000 emails and 10 PushMirror challenges. Competitors in this table do not offer WhatsApp.
03
Pro: email + WhatsApp + PushMirror
$12.99/mo for 120k email, 15,000 WhatsApp notifications, and 8,000 PushMirror challenges/mo. One API key. Switch channel per request.
04
Your provider, our DX
Not a Resend clone. You keep SendGrid, Gmail, SMTP, and your WhatsApp line. Zindua adds templates, i18n, multi-project keys, and one SDK. We route. We do not host your mail servers.
05
Collaborate on Free
2 workspace seats on Free. Pro and Me raise the cap. Limits follow your plan in the dashboard.
WhatsApp free tier
WhatsApp on the same product.
None of the email ESPs below ship WhatsApp on the same product. Zindua does. OTP, alerts, and other transactional messages share the Free quota.

Free email volume
Email-only, same free desk.
Zindua Free includes 8,000 emails/mo plus WhatsApp and PushMirror. Emails/day is monthly divided by 30, indicative only.

Paid tiers
Headline list prices.
Zindua Pro: 120k email + 15k WhatsApp + 8k PushMirror/mo. Me: unlimited email and WhatsApp + 100k PushMirror (fair use). Throughput still depends on the Gmail, SMTP, or WhatsApp line you connect.

Zindua is an orchestration product: templates, API, WhatsApp, and optional DNS guidance on Pro. Competitors in this table are ESPs with their own delivery network. Choose an ESP when you want them to send everything. Choose Zindua when you want one developer surface on top of providers you already use.
