The SendGrid agency.Inbox, not spam.
Spun up with just an API key, SendGrid quietly drops your mail in spam and you never find out why. We authenticate the sender with SPF, DKIM and DMARC, build your templates, warm the IP, and wire the Event Webhook into your stack.

GeminiA SendGrid agency gets you into the inbox, not just sending.
Anyone can paste in an API key. Authenticating your domain, warming an IP, wiring the webhooks and keeping your reputation clean is a different job. Here are the four things we own.
- Sender setup
SendGrid set up so your mail actually reaches inboxes
An API key alone gets your mail flagged. We do the full sender authentication: domain authentication with SPF, DKIM and DMARC alignment, branded link tracking, and a from-address that passes the major mailbox providers. We pick between the Email API and the SMTP relay based on how your app sends, wire the keys with the right scopes, and set up subusers so transactional and marketing traffic stay separated.
See a typical setup - Deliverability
Dedicated IPs and the IP warmup most people skip
On a shared IP your reputation is hostage to other senders; on a fresh dedicated IP, blasting day one gets you throttled. We decide which you actually need by volume, then run the IP warmup schedule that builds reputation gradually. We set up suppression management so bounces and unsubscribes are handled cleanly, and watch deliverability instead of assuming a green dashboard means inbox placement.
See the method - Templates & API
Dynamic templates wired into your app and your stack
We build your transactional email on SendGrid dynamic templates with Handlebars, so receipts, password resets and notifications render right across clients, and your devs push variables instead of HTML. For marketing, we set up Marketing Campaigns and segmentation. Then we wire the Event Webhook so opens, clicks, bounces and spam reports flow back into your stack, and connect it to your CRM or product backend.

Migrated off your old ESP, without a reputation crash
Switching senders is where deliverability goes to die if you rush it. We migrate you off your old ESP or onto a clean SendGrid account, move templates and suppression lists, re-authenticate your domain, and warm the new sending so the cutover doesn't tank your inbox rate. We're an automation and AI agency first, so this plugs into how your product already sends mail.

We set up SendGrid like email infrastructure, not a quickstart.
Most SendGrid setups break the same way: an API key pasted in, no domain authentication, no IP warmup, and mail quietly landing in spam while the dashboard stays green. So we treat it like infrastructure: authenticated sender, templates tested across clients, an IP warmed properly, and a feedback loop that catches a deliverability dip before your users do.
- Audit · map how you send today, your domain auth, and where mail is getting lost
- Setup · sender authentication, API or SMTP, templates and suppression, safe by default
- Warm · dedicated IP decision and the IP warmup schedule that builds reputation
- Monitor · Event Webhook and deliverability tracking so a dip surfaces before users notice
We send on SendGrid every day.
We don't sell a partner tier. We run real transactional and marketing email on SendGrid ourselves, so we set it up the way it actually behaves: authenticated sender, an IP warmed on a real schedule, suppression handled, and the Event Webhook feeding our stack. That's exactly what's missing when a setup ends at pasting in an API key.
- We send real transactional and marketing email on SendGrid ourselves, so we set up sender auth, warmup and webhooks the way they actually behave, not the way a quickstart suggests.
- We're honest about the catch: deliverability is ongoing work and shared-IP reputation can bite, so we tell you what staying in the inbox actually takes.
- You leave autonomous: the setup lives in your SendGrid account and your repo, so your team owns it without us.
- No badge to sell. We're judged on whether your mail keeps landing in inboxes after we leave, not on a partner tier.
SendGrid at the core, your email stack around it.
We configure the parts that turn a sending account into reliable inbox placement, then connect them to how your product already sends mail. Here's what a real setup covers.
- Setup
Sender authentication
We set up domain authentication with SPF, DKIM and DMARC alignment plus branded link tracking, so mailbox providers trust your domain instead of dropping you into spam or the promotions tab.
- Setup
Email API & SMTP relay
We wire the Email API or the SMTP relay to how your app actually sends, with scoped API keys, retries and the right endpoints, so transactional mail goes out reliably and you can debug it when it doesn't.
- Setup
Dynamic templates
We build your transactional mail on dynamic templates with Handlebars, version-controlled and tested across clients, so receipts, resets and alerts render right and your devs send variables, not hand-edited HTML.
- Setup
Dedicated IPs & IP warmup
We decide whether you need a dedicated IP by volume, then run the IP warmup schedule that builds reputation gradually instead of getting your fresh IP throttled on the first big send.
- Setup
Event Webhook & analytics
We wire the Event Webhook so opens, clicks, bounces, spam reports and unsubscribes flow back into your stack, then set up the monitoring that tells you about a deliverability dip before your users do.
- Setup
Suppression & subusers
We set up suppression management so bounces and unsubscribes are honored automatically, and use subusers to separate transactional from marketing traffic so one bad campaign can't sink your password resets.
We check why your mail isn't landing, you leave with a plan.
Before quoting anything, we take 60 minutes to look at how you send, your domain authentication, your bounce and spam rates, and where mail is getting lost. You leave with an honest read on what SendGrid fixes, what to set up first, and what your deliverability really needs. Zero pitch, just an engineer's take on your sending.

- Whether you need a dedicated IP and how to warm it
- A frank take on what SendGrid won't fix
How we run a SendGrid setup.
Five steps, in order. We don't send at volume before the sender is authenticated and the IP is warmed, we don't migrate without a parallel warmup, and your team owns it at the end. Each step has a deliverable and you sign off before we move on.
- Step 1 · Sending audit
Map how you send and where mail is getting lost
We look at how your app sends today, your current ESP, your domain authentication, your bounce and spam rates, and whether you're on a shared or dedicated IP. Half the value is telling you whether your inbox problem is a SendGrid setup issue, a content issue, or a reputation you already burned, so you don't pay to fix the wrong thing.
- Step 2 · Authenticated setup
Set up SendGrid so providers trust your domain
We do the full sender authentication: domain authentication with SPF, DKIM and DMARC alignment, branded link tracking, scoped API keys, and the Email API or SMTP relay wired to your app. We set up dynamic templates and suppression management, and separate transactional from marketing with subusers. You sign off before any production mail goes out.
- Step 3 · Warm the sending
Decide on a dedicated IP and warm it properly
We decide whether your volume justifies a dedicated IP or whether a well-managed shared pool is smarter, then run the IP warmup schedule that ramps volume gradually so you build reputation instead of getting throttled. If you're migrating, we warm the new sending in parallel so the cutover doesn't crater your deliverability.
- Step 4 · Wire the feedback loop
Connect the Event Webhook and your stack
We wire the Event Webhook so opens, clicks, bounces, spam reports and unsubscribes flow back into your product, CRM or data warehouse. For marketing we set up Marketing Campaigns and segmentation. The point is a feedback loop that surfaces a deliverability dip early, not a dashboard you check after users complain mail never arrived.
- Step 5 · Hand over & monitor
Hand it over, then keep an eye on the inbox
We document the setup in your account and repo so your team owns it, and set up the monitoring that flags reputation drops. Deliverability isn't set-and-forget, so we're upfront that it needs ongoing attention. If you want us watching it for you, we talk about that separately. If you want to go deeper in-house, our training covers it end to end.
We're judged on the mail that lands.
No partner badge to display, so we lead with what matters: feedback from the teams whose SendGrid setup we ran, and whether their mail kept reaching inboxes after we left. Our Trustpilot reviews come from those teams, not from a marketing deck.
- The setup lives in your SendGrid account and repo, owned by your team
- Sender authentication and IP warmup done before sending at volume
- Suppression honored and the Event Webhook feeding your stack
- Trustpilot reviews come from the teams we set it up for
The questions we get asked on repeat.
What does a SendGrid agency actually do?
A SendGrid agency sets up your transactional and marketing email so it lands in inboxes instead of spam. We do the sender authentication (domain auth with SPF, DKIM and DMARC), wire the Email API or SMTP relay to your app, build dynamic templates, decide on dedicated IPs and run the IP warmup, set up suppression management and the Event Webhook, and migrate you cleanly off your old ESP. The point is reliable email your team owns, not a SendGrid account nobody configured properly.How much does a SendGrid setup cost?
It depends on scope: authenticating a domain and wiring transactional templates is nothing like migrating off another ESP with a dedicated IP warmup and full marketing setup. We don't throw out a flat package. We start with a free 60-minute audit to find what's actually hurting your deliverability, then quote a fixed scope. The SendGrid plan itself you pay Twilio directly; we set up the account and sending so the bill and the inbox rate stay predictable.Will SendGrid fix my deliverability problems?
Honestly, not on its own, and we'd rather say so. SendGrid gives you the tools (sender authentication, dedicated IPs, suppression management, deliverability monitoring) but a green dashboard isn't inbox placement. Deliverability is ongoing work: it depends on your content, your engagement, your list hygiene and your sending reputation, not just the platform. We set up everything correctly and tell you honestly what staying in the inbox will take from you after we leave.Should we use a dedicated IP or a shared IP?
It depends on volume and consistency. On a shared IP your reputation rides on other senders in the pool, which can bite if one of them sends badly. A dedicated IP gives you control but needs steady volume and a proper IP warmup, or it gets throttled. SendGrid generally points to a dedicated IP from higher monthly volume. We look at your real numbers and recommend the one that helps your inbox rate, not the one that sounds more serious.Can you migrate us from another ESP to SendGrid?
Yes, and migration is where deliverability quietly dies if it's rushed. We move your templates and suppression lists, re-authenticate your domain with SPF, DKIM and DMARC, wire the Email API or SMTP relay, and warm the new sending in parallel so the cutover doesn't crash your reputation. We keep the old sender live until the new one is trusted, then switch. The goal is a clean migration where your users never notice the mail moved.Email API or SMTP relay, which should we use?
The Email API is the recommended path for most apps: it's faster, gives you richer control and better error handling, and supports dynamic templates and the Event Webhook cleanly. The SMTP relay is the right call when your existing system already speaks SMTP and you don't want to rewrite it. We look at how your app sends today and wire whichever fits, with scoped API keys and retries so transactional mail goes out reliably.Can you wire the Event Webhook into our stack?
Yes, that's where SendGrid earns its place beyond just sending. We wire the Event Webhook so opens, clicks, bounces, spam reports and unsubscribes flow back into your product, CRM or data warehouse, with the signature verification that keeps it secure. That gives you a real feedback loop: you see a deliverability dip or a bounce spike early, instead of finding out when a user says they never got the email.Is SendGrid the right tool for us?
Not always, and we'll tell you straight. SendGrid is strong for transactional and marketing email at scale, with a solid Email API and deliverability tooling. But if you only send a trickle of mail, simpler tools may fit better, and shared-IP reputation on lower tiers can be a real downside. If a dedicated cold-outreach or creator-focused tool fits your case better, we'll say so in the audit rather than sell you a setup you don't need.
Stop landing in spam. Set it up right.
A 60-minute audit, your sending mapped, a setup plan with sender authentication and IP warmup baked in. If your team can run it in-house after setup, we'll hand you the playbook. If we're the right fit, we handle it.
