Which one is for you

Pick MailChannels if

  • Fits if you run a platform that sends mail for many customers
  • Works for developers who want a free tier to prototype on

Look elsewhere if

  • Skip it if you want email support on a small plan, as it is listed only from 300,000 emails a month
  • Tight if you stay free, because it stops at 100 emails a day with no overage
  • Watch out: the page says no tier sits between the free plan and the 10,000-email paid plan
  • Watch out: Outbound Filtering for hosting providers is a separate product from $99.99 a month
  • Not for you if you want open and click tracking for free, as it comes with the paid plan

Pick SMTP2GO if

  • Fits if your office printers, scanners or old systems need somewhere to send mail from
  • Works for people who look after email for several clients and want subaccounts on a paid plan

Look elsewhere if

  • Not for you if your app needs to receive and read incoming email
  • Tight if you're staying free, at 1,000 emails a month and 200 a day, with no way to buy more
  • Skip it if you only have a Gmail or Yahoo address to sign up with
  • Pricey if you need a dedicated IP or email testing, which start with Professional at $75 a month
  • Watch out: the free plan keeps 5 days of reports, and chat and phone help stop after 14 days

How we grade them

2.8GPAMailChannelsGood2.2GPASMTP2GOFair
Value for money
B$10 a month for up to 10,000 emails, the top of the category's cheaper quarter, rising to $30 at 100,000.
CGraded on 50,000 emails a month: Starter is $30 a month at that volume, with two months free if you pay yearly. That sits in the middle of what this category charges for that much sending. A dedicated IP and email testing need Professional at $75.
Free plan and trial
B3,000 emails a month, 100 a day, 3 domains and no overage charges, which a small project can live on, though open and click tracking need a paid plan.
CFree for good with no card: 1,000 emails a month, but only 200 a day, with 5 days of reports, and extra emails can't be bought. Chat and phone help last 14 days. Enough for a test, tight for a live app.
Features
BA REST API and SMTP, per-tenant sub-accounts, bounce and complaint webhooks, threat filtering and approval hooks. The core sending job is covered.
CAPI and SMTP sending, automatic SPF and DKIM, delivery reports with bounce alerts, blacklist monitoring, three data regions and subaccounts. It does the sending job fully, but that's a smaller job: nothing on record covers receiving email or templates.
Ease of use
CNo store rating on record. You verify a sending domain with DNS records and wire up SMTP credentials or an API key before the first email goes out.
CJudged on how fast a developer sends a first email: copy the SMTP details or use the API, with code examples in five languages, once your domain is added. No rating on record. Sign-up refuses Gmail and Yahoo addresses, so you need a work domain.
Platforms and integrations
BA web console and an API; the listing names Laravel, Symfony, Nodemailer, Django, FastAPI and cPanel.
BWeb, with an SMTP relay and REST API that work from apps, servers and devices, plus WordPress, Google Workspace, Salesforce, Zoho CRM, Pipedrive, WHMCS, Laravel and Django. No desktop or phone app, so B is the top.

    Key features

    MailChannels

    REST API and SMTP relay
    Mail goes out through a REST API or an SMTP relay with the same controls on either path.
    Sub-account isolation
    Each tenant, workspace or AI agent gets its own sender identity, with reputation, limits and policy scoped to it.
    Bounce and complaint webhooks
    Webhooks report delivery events, including feedback-loop complaints, so a platform can retry, pause or suspend a single sender.
    Inline threat filtering
    Outbound messages are scanned for phishing, malware and known abuse patterns before they leave the network.
    Approval hooks for agents
    A human or programmatic checkpoint can be placed in the send path, which the vendor suggests for AI agents sending high-risk messages.

    Real-time reports follow each email to delivery and show bounces, spam complaints and unsubscribes, with weekly summaries and alerts on sudden bounce rises.
    Automatic SPF and DKIM
    Domain authentication is handled for you, along with feedback loops, blacklist monitoring and spam trap detection on every plan.
    Data centers in three regions
    Choose to send from and store data in the US, Europe or Australia, with best-path routing to the nearest location.
    Email testing
    Professional adds previews in more than 40 email clients and checks against major spam filters before you send.
    Subaccounts
    Paid plans can split sending into subaccounts, which suits agencies and managed service providers looking after several clients.

    How this page was made

    • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
    • The grades are our own, from each tool’s review or report card. The GPA is their average.
    • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
