Yes, you can upgrade, downgrade, or switch between monthly and yearly billing anytime from your billing settings. Annual billing plans automatically include a 17% discount (equivalent to 2 months free).
Payments are processed securely through our Merchant of Record, Dodo Payments. We support UPI (Google Pay, PhonePe, Paytm), RuPay, Visa, Mastercard, American Express, Netbanking, and international cards across 150+ countries with automated GSTIN/VAT tax receipts.
SendOFF does not drop your emails unexpectedly. As you approach 80% and 95% of your quota, we dispatch proactive alerts. Additional sends are billed at transparent overage rates (₹0.03/email), or you can upgrade to the next tier with one click for immediate higher limits.
Yes! SendOFF provides high-performance TLS SMTP relays on standard ports (587 and 465) alongside our REST API. You can drop SendOFF into Nodemailer, Django, Laravel, Ruby on Rails, or Spring Boot simply by swapping your SMTP credentials.
We operate our own bare-metal KumoMTA sending clusters with isolated dual-lane IP queues (transactional OTP lane separated from bulk mail). We automatically provision 2048-bit DKIM keys, enforce strict SPF/DMARC alignment, and maintain automated feedback loop (FBL) reputation monitoring.
Dedicated IPs are available on Growth and Scale tiers. Our automated IP warmup algorithm gradually scales your volume according to ISP thresholds, ensuring pristine sender reputation from day one.
You can cancel your subscription at any time with a single click from the customer portal in your billing settings. Your plan features and quotas will remain active until the end of your current prepaid billing cycle without further charges.
We support high-throughput senders sending tens of millions of transactional emails monthly.
