SendOps

Open-source stacks + SES reduce vendor lock-in and cost but be ready for trade-offs: more DIY maintenance, ops overhead, and slower support than a dedicated control plane like SendOps. Sometimes the middle ground—cost-effective, no-code layers—best balances control with operational sanity.

🚀 Want to build a #Resend-like product (dev-friendly transactional email API with templates, analytics, webhooks) but 5-10x cheaper? Skip Resend's markup + #Amazon SES costs. Use open-source @useSend_com + ZeptoMail. Full control, no vendor lock-in. Thread 👇

Spam and phishing tools are essential, but true email ops maturity means real-time visibility into reputation and proactive alerts—without the overhead of migrating away from SES or building complex in-house systems. That’s where a dedicated SES control plane adds game-changing value.

@quartzdevgg @resend When frustration with SendGrid’s pricing hits, don’t just switch to another costly managed provider. Consider SendOps—no domain caps, no per-email markups, just SES rates plus a control plane that scales with your team and spares weeks of rebuild. Happy to show a demo!

@resend my business wants to move over. We don’t like sendgrid. But it would cost us so much more for literally no cost to u. Rethink ur domain cap. Please.

@notrab @resend Great to see tools like @resend making email infrastructure more accessible. For teams already on SES looking to avoid complex rebuilds or pricey per-email fees, control planes like SendOps add the operational maturity needed—without losing the delivery cost benefits of SES.

There's now an article on how to create this with @resend over on my blog! notrab.dev/blog/build-you…

@TheDevSaha @yashpanditrao Interesting insight on 'sg_machine_open'. tracking human vs. machine opens is a smart move for better email engagement metrics. This kind of signal is critical for observability tools that want to provide accurate campaign performance without skewed data from automated previews.

@yashpanditrao Probably the Mailbox previews automated - Sendgrid passes a parameter called ‘sg_machine_open’ to detect if it was a human open or a machine open. At least a high degree of probability.

Turns out Mailchimp open rates are not very reliable. We ran a campaign that showed decent open rates, but the conversion rate was abysmal. To understand what was going wrong, we started calling people who were marked as having opened the email. Almost everyone said the same thing: they had never opened it. The email was not in spam either. It had landed. Very weird, and a good reminder that open rates are a weak metric to rely on.

@csaba_kissi @MusharofChy Love SES but juggling multiple providers? If you want SES-level cost efficiency without building a full observability stack, a control plane like SendOps gives you dashboards, alerts, and team access—no migration, no SDK swaps, just better insights on your terms.

@MusharofChy I mostly use SES. Still have something on Resend and Mailgun.

Services for web developers Full-stack hosting - Sevalla CDN + Domain registration - Cloudflare Transactional emails - Amazon SES Auth - Better Auth Error tracking - Highlight .io Uptime monitoring - Better Stack Search - Typesense / Meilisearch Payments - Stripe / Creem CI/CD - GitHub Actions

Rich profiles are great, but they don’t solve the core friction of email ops on SES: no dashboards, no alerting, no easy team access without AWS keys. Building those from scratch wastes weeks. SendOps adds that control plane instantly, no code changes, at a fraction of managed provider costs.

AtlasOra has built an agentic host acquisition pipeline. 7 specialized AI agents running real outreach to Spanish property managers right now. Hunter → Triager → Enricher → Pitcher (native multilingual) → Compliance Guardian → Sender (Mailgun) → Conversationalist. Every prospect gets a rich structured profile (holder type, property count, pain points, etc.) so the agents auto-select language, tone, and angle with 4-layer compliance. This is the operational leverage tokens are supposed to fund. $AORA ships Thursday on Aerodrome Ignition. Agents do the work. Humans reap the rewards.

@anitakirkovska @TheCodingSloth1 @beehiiv @resend Totally agree: drafts are just the start. The real win is a reliable scheduling system backed by clear visibility and alerts so your team can act fast. That’s where a purpose-built email control plane like SendOps shines: systematic ops without overhauling your sending stack.

@TheCodingSloth1 @beehiiv @resend good overview - i think we care less about writing drafts and more about scheduling, and having a systematic process where our agents can help

I'm looking to move our newsletter in a new platform. The top two options right now are @beehiiv and @resend Resend seems like it's very ai-native, vs beehiiv is feature-rich and has network effects any tips? or other options that we've missed?

@Mail_Gun Operational hiccups like this highlight why so many teams struggle balancing cost and reliability in email ops. When control planes go down, it can halt critical workflows. This is why having a dedicated, resilient SES control plane without vendor lock-in matters more than ever.

@7hakurg Resend’s DX shine comes at a steep price: great if volume is low, but costly as you scale. For teams already invested in SES wanting operational tools without a full vendor rewrite, SendOps adds dashboards, alerts, and team controls without markup or code changes.

First, why Resend is great but expensive: - Beautiful API + SDKs (Node, etc.) - React Email templates - Webhooks, analytics, domain management - But it's basically a fancy wrapper on Amazon SES → you pay premium for the DX. SES alone: ~$0.10 per 1k emails. Resend: free tier tiny, then paid plans with markup.

This is an engineer's runbook for fixing AWS SES email deliverability issues before AWS places your account under review or pauses your sending exact thresholds, the CLI to check them, a triage playbook for the first hour after a review notice, and the bounce and complaint handling pipelines so it doesn't happen again. blog.sendops.dev/blog/fix-aws-s… #aws #email #ses

High bounce rates and elevated complain rates can result in banning your AWS SES account immediately. This can really hurt your operations. Here is a detailed guide on preventing those and what to do in case the block happnes:

@fayazara totally agree. you can lower the email to match SES though! ;)

The Cloudflare $5/mo plan is honestly absurd Workers - 10M requests D1 - 25B reads, 50M writes KV - 10M reads, 1M writes R2 - 10 GB storage, zero egress Email - $0.35 for 1000 emails Browser - 10 hours per month You also get Durable Objects, Queues, Workflows - included, Unlimited Hyperdrive queries, Vectors.

@dancolta Good ideas (although Proxycurl has shut down). On the email side you can get much higher deliverability by using SES + Sendops.dev

Most "Apollo alternatives" are just cheaper Apollos. The real move: stop renting the stack. Postmark + Hunter + Proxycurl + GPT-4o-mini = $74-$172/mo ~42 hrs to build. Pays for itself in 17 months. Link below 👇

@mddanishyusuf Can we suggest an even cheaper and better option? AWS SES + SendOps.dev it's the killer combo!

1 million emails/month: Postmark: $1,206 Resend: $650 SendGrid: $600 Cloudflare: $354 Mailchimp: $800+ Maillayer: $99. Once. Forever. Self-hosted, yours forever: ↳ SES, SendGrid, Mailgun, Postmark ↳ Campaigns, sequences, transactional API ↳ One-click Railway deploy. Your server. Your data. Your emails. → maillayer.com

@abhi100425 It’s a huge blindspot, especially for teams juggling multiple providers. Managing SPF complexity should be part of your email ops toolkit, not an afterthought.

@abhi100425 SPF limits are a silent killer for email deliverability; once you hit 10 DNS lookups, you’re in PERMERROR territory, and every email tanks.

Contact form emails stopped arriving? 5-step diagnostic, in order: 1. Test the mailer in WP Mail SMTP > Tools 2. Check the From email address 3. Verify SPF 4. Check Email Logs for actual send status 5. Test to a fresh inbox Step 2 catches more than the other 4 combined. #WordPress #EmailDeliverability

@yegispnk @amazon @awscloud @OVHcloud @ovh_support_us @Yahoo @yahoomail @sendgrid @Google @gmail @Microsoft @Outlook If you're already using AWS, you might want to try replacing SendGrid with AWS SES and reduce your bills and improve deliverability. If you combine that with SendOps.dev then it's even better!

@saasalecom @marclou @zenorocha If you ever want to reduce your costs, switch to AWS SES (which gives you excellent deliverability) and combine it with SendOps.dev and you'll get reputation management, metrics and templates via a git workflow.

@marclou @zenorocha And that's the best kind of endorsement. When something just works better, you switch even if you hate switching. Curious what the specific pain point was with Mailgun that Resend solved.

Resend started as a frustration. As an indie hacker, working nights and weekends, I felt like every email service was built for someone else. So I decided to create my own. Today @marclou runs 33 startups solo on it. I know Resend is not for everyone (and that's okay), but it feels nice to be able to build products for other indie hackers.

@ahmet_php @nestersk We respectfully disagree! Use SES with us (Sendops.dev) and you don't have to hate anyone! ;)

@nestersk but asking unironically, does the higher priced service (postmark in this case) have better delivery rates as a rule?

If someone tells you the cost of a lightweight email service is an issue, you can almost be certain they're not doing email marketing or thinking highly of it. If you only run transactional emails and do it at scale, the bill might, indeed, be a constant reminder of the 'money I could save'. But once you look at ROI of email marketing, whatever gets you sending them faster and with high deliverability, is king.
