SMTPProvider

What SMTPProvider is

SMTPProvider is an SMTP relay and email API service run by SMTP Provider Pvt Ltd, which gives its office as South City Businesspark in Anandpur, Kolkata, West Bengal, India. It carries two kinds of mail: bulk promotional email such as newsletters, campaigns, product launches and customer updates, and transactional email that a website or application triggers, such as OTPs, password resets, invoices and order confirmations. The site's own tagline is "Next level of Unlimited Email Marketing at an Affordable Price."

The offer is sending infrastructure rather than a full marketing suite. A customer buys a plan, receives SMTP credentials and plugs them into a website, an app, a CRM, a shop or an existing email tool. Pricing runs from small shared-IP plans for low volumes up to unlimited plans on dedicated IP addresses, and the buy page names three routes to choose between: shared SMTP, business SMTP and dedicated SMTP.

What a sender gets

SMTP relay. The core product is authenticated outgoing SMTP. The buy page describes relaying outgoing email "from your website, app, CRM, server, or business platform through authenticated SMTP." Setup runs in four steps: choose a plan, create an account and open the SMTPProvider dashboard, copy the SMTP host, username, password, port and encryption details, then connect the website or app and start sending. The FAQ adds that a new customer receives two emails after purchase, a receipt and a setup guide, and that the auto-generated password in the welcome mail goes into the email program while the password chosen at checkout is for the personal login. Where a network blocks port 25, the FAQ says to switch to port 587 or 2525, and it walks through a Telnet test for checking that the SMTP server answers.

Email API. Besides SMTP there is API sending, which the buy page aims at "SaaS platforms, dashboards, backend systems, and custom applications." The API documentation is split into a transactional and a promotional section. A post on the company's blog explains the general flow: obtain API credentials, pick an endpoint, build a request with the recipient, subject and body in your own programming language, and send it with an HTTP client.

Promotional and transactional mail from one account. The Shopify page frames this as "Marketing + Transactional in One Place": bulk campaigns, promotions, order updates, alerts and important customer emails from one provider. On the transactional side the buy page lists OTPs, password resets, invoices, account verification emails, contact form emails, order confirmations and application notifications.

Shopify. SMTPProvider advertises a Shopify app and runs a dedicated page for Shopify stores. It promises simple setup and delivery of both promotional and transactional mail for sales campaigns, product launches and order updates, with a "Start Free" button to begin. The same page mentions custom onboarding, setup help, deliverability support, IP options and a customer dashboard, and says plans start "from just $2" and can move to a custom setup for larger sending needs.

Websites, frameworks and CRMs. The supported platforms are WordPress, PHP, WooCommerce, Python, Node.js, Laravel, CRM tools and email platforms. The buy page's FAQ confirms that SMTPProvider can be connected with WordPress, WooCommerce, Laravel, PHP, Node.js, Python, CRM tools, landing pages and custom applications.

Templates. The feature menu names a template builder, and the Shopify page's FAQ describes a visual Template Editor and an Email Template Builder that use AI to produce ready-to-send drafts and layouts. Templates export as clean HTML, accept personalization variables such as a first name or company, and the site says they are responsive and dark-mode aware. The unlimited plans also list a customized email template.

Tracking and retries. Delivery reports sit in the customer's account. The FAQ describes opening the statistics menu, choosing a date for the log files, and reading successful sends marked in green and failures in red. If a recipient's server is offline, the system keeps trying to deliver the message for three days.

Deliverability tools. The unlimited plans list DKIM, SPF and DMARC setup, a feedback loop, rDNS, a Mail-Tester report and fresh IPs. The feature menu also names a warm-up process and an SMTP server test. The buy page gives sending advice in its own words: send only to opted-in or permission-based contacts, avoid purchased or scraped lists, warm up new domains and IPs gradually, and track bounce rates, complaints and engagement. The FAQ also explains what an SPF record does.

Security and message handling. The FAQ says the servers are used exclusively for outgoing email, that sent emails are not stored on the SMTP server, and that the company keeps "high security standards" with regular system updates. It also says the company does not pass email addresses on to third parties. The maximum message size is 25 MB; the FAQ advises against large emails because they can cause trouble at receiving servers.

Plans, prices and terms

Promotional plans. The shared-IP promotional plans, which the buy page calls "cost-effective and reliable email marketing services based on cloud computing", start with Plan P2 at $2 a month for 1,000 emails, Plan P3 at $5 a month for 4,000 emails and Plan P4 at $10 a month for 10,000 emails. Each lists shared IPs and live online support, and a link leads to the full plan list.

Unlimited SMTP plans. For high volumes there are three monthly unlimited plans, which the page says give "access to unlimited email delivery without any restrictions" and calls ideal for big businesses. Unlimited P1 costs $400 a month with a listed speed of 3000 per hour and 5 dedicated IP addresses. Unlimited P2 costs $700 a month with 6000 per hour and 10 dedicated IPs. Unlimited P3 costs $1000 a month with 9000 per hour and 15 dedicated IPs. All three list unlimited subscribers, a monthly subscription, a setup delivery time of 24-48 hours, DKIM, SPF and DMARC setup, feedback loop, rDNS, a Mail-Tester report, fresh IPs, unlimited sending domains, a customized email template and live support. Prices can be shown in USD, INR, GBP or CAD.

Setup time. According to the buy page's FAQ, credentials arrive within 24-48 hours of payment. Most standard plans are set up within 24 hours, while dedicated IP plans may take up to 48 hours so that SPF, DKIM and DMARC are in place.

Smaller subscriptions in the FAQ. The FAQ describes a basic subscription for a single user that allows 75 emails a day, a Family subscription shared across up to 3 addresses with the same 75 daily emails, and three premium subscriptions for work groups and companies. Daily volume can be raised from 75 to 125 emails by buying extra emails from the account menu, and an email buffer adds headroom so the sender does not run out. Each message can go to 10 normal recipients plus 65 in BCC or CC, and every recipient counts as one email sent.

Trial, payment and renewal. The site invites new customers to "Try For Free", and the FAQ describes the step after the free trial ends: log in, click START SERVICE and pick a subscription. Payment runs through PayPal or Razorpay, and the FAQ says card payments go through PayPal's secured server. The company sends a renewal reminder at least 10 days before a subscription expires and a second notice two days before; a subscription the customer does not extend simply expires.

Policies. SMTPProvider publishes an anti-spam policy that bars unsolicited commercial email "regardless of the opt-in lists", holds customers responsible for any spamming from their account, and reserves the right to suspend, terminate or restrict an account, pursue civil remedies and inform law enforcement where a violation is believed to be criminal. The site's policy pages also include a Can Spam Act page and a refund policy.

Support. Support runs by phone, by email at info@smtpprovider.com and through live support, and the site describes 24/7 technical support on its plan pages.

Who it suits and who it does not

SMTPProvider suits small shops, WordPress and WooCommerce sites and developers who want an inexpensive SMTP login for the mail their site or app sends, and who design campaigns in a separate tool or with the template builder. The $2 entry plan makes a first test cheap, and Shopify stores get their own app. High-volume senders who want their own IP reputation have the unlimited plans, with 5 to 15 dedicated IPs at a flat monthly price, which keeps the bill predictable for a business sending large volumes every month.

It is a weaker fit for marketers who want list management, segmentation and automated journeys in one place: the company's focus is the sending pipe, and its pages describe delivery logs rather than campaign analytics. Buyers should also read the plan pages closely, because the FAQ's daily-limit subscriptions and the monthly plan tables describe the offer in different terms, and it is the plan table a new customer actually orders from.
