Start with the big one. Early in 2026, Gmail switched on its “Gemini era”: AI summaries, AI replies, AI calling the shots on what counts as important. Apple had already beaten them to it, generating little summaries that stand in for your preheader before anyone opens anything. So for the first time, a machine decides what surfaces and what gets flattened into a one-line gray blurb. Your supporter is the second one to see it.

You can already watch this in the data. Once the summaries went live, reported opens climbed while clicks slipped, because people read the recap and never tap through. Landing in the inbox used to be the whole goal. Now you have to clear a second bar: being judged relevant enough to surface at all.

Getting delivered is the easy part now. Whether the AI decides you’re worth surfacing is the whole game.

The play. Write for two readers: the human and the bot. Lead with your one concrete, useful thing, whether that’s the deadline, the number, or the place to show up, so it survives the summary. Anything the AI would trim, trim it yourself first.

It gets stranger. At its 2026 developer conference, Google unveiled Gemini Spark, a 24/7 agent that lives in your inbox and actually does things: it triages mail, drafts replies, chases down loose threads, and yes, it can unsubscribe for someone. The inbox now filters, summarizes, and acts on your mail directly.

A campaign should care about two things here. An agent that triages on autopilot can bury a sender it reads as noise, or unsubscribe from it, with no human in the loop. And supporters are starting to ask their assistants questions like “any donation requests worth my time?” That creates a new job for campaigns: being the answer the AI gives back, not just another message sitting in the pile. The marketing world already has a name for it, answer engine optimization, and it’s headed for politics fast.

The play. Win the agent’s trust the way you’d win a person’s, with a consistent sender identity, clean engagement, and content people keep. And keep your candidate’s name, positions, and basic facts consistent everywhere online, because that’s what assistants reach for when a supporter asks about you.

SPF, DKIM, DMARC, one-click unsubscribe. None of that is an advantage anymore; it’s the cover charge. Late last year Gmail quit quietly shuffling questionable mail into spam and began rejecting it outright, and a real chunk of senders still haven’t fully complied. They’re paying for it in placement.

The problem for political senders comes after authentication. Once everyone is authenticated, the thing standing between you and the inbox is your spam-complaint rate, and the ceiling is a merciless 0.3%. That blast-it-daily, FINAL NOTICE on everything style that made bank a couple cycles ago is precisely how you train people to hit “report spam” and push yourself over the line. Perfect authentication won’t save you from it.

The play. Treat 0.3% as a wall you don’t touch. Put one-click unsubscribe on every send. And clear out your dead weight before it complains, because an unsubscribe stings for a second while a spam complaint leaves a mark.

Your reputation used to ride on your IP address. Now it rides on your domain. The providers made the sending domain the primary signal and stopped reporting IP reputation at all, which tracks: an IP is rented and shared, while a domain is actually yours.

BIMI puts a verified logo right beside your message once your DMARC is locked down, a small trust badge in an inbox crawling with impersonators. And DKIM2, the first serious upgrade to email signing in over a decade, should start showing up at the major providers by the end of the year, shutting down the “replay” trick spammers use to ride a good sender’s name. The direction is clear: the inbox wants verifiable trust, not claimed trust.

The play. Lock down DMARC, get DKIM clean on every domain you send from, and start the BIMI process so your logo shows up verified. Treat your domain as an asset to protect, not a box to check once.

Anyone can produce slick fundraising copy now. You can, your opponent can, and so can everyone with a candidate-shaped logo. When good copy is free and endless, it stops being an edge. And the AI minding the inbox is built to detect one thing above all: whether there’s real value in it for the reader.

That’s the bind. Polished but hollow gets flagged the same as spam. The campaigns that break through will pour their effort into what a model can’t counterfeit: a genuine voice, claims that are specific and true, and segments tight enough that the message fits the person reading it. Worth a legal note, too. AI that fabricates a promise or an ask to close a gift is starting to attract scrutiny, and “the bot wrote it” is not going to hold up.

When polished copy is free, the differentiator is honesty.

The play. Let AI hand you a rough draft and nothing more. Put the time you save into the two things that actually move money: sharper segments, and saying something only your campaign could honestly say.

Quietly, the tool email marketers leaned on for a decade has been coming apart. Third-party cookies are blocked or unreliable nearly everywhere, and Apple’s privacy features already hollowed out the tracking pixel, which is a big reason half your “opens” aren’t real. Rented, matched, and cross-site audiences thin out a little more every month.

What survives is your own data, and it’s the good stuff. First-party data is what supporters do on your turf: your list, your site, your donation history. Zero-party data is what they tell you outright, like a survey answer, a stated preference, a “text me, don’t email me.” That’s the durable, consented, can’t-be-deplatformed asset, and most campaigns are sitting on a mountain of it (the voter file, for starters) that they barely use. The ones who win in 2026 ask for it, keep it, and act on it.

The play. Bake collection into everything: preference centers, short surveys, the donation flow. Use server-side tracking so you stop leaking signal to ad blockers. Then build your segments on what people actually told you, not on a pixel that won’t fire.

You’re probably still putting open rates in your reports. It’s time to stop. Apple auto-loads tracking pixels and pads roughly half of all opens, and AI summaries blur the rest, since an “open” might just be a bot skimming the message so your supporter doesn’t have to. An open-rate slide in 2026 is a slide full of fan fiction.

The useful metrics split into two buckets. Engagement quality covers clicks, replies, conversions, and the time someone actually spends reading. List health covers complaint rate, bounce rate, and authentication pass rate. The catch is that none of those are just scoreboard stats now. They’re the same signals the inbox reads to decide your fate, so tracking them well has quietly become part of deliverability.

The play. Rebuild your dashboard around real actions and list health. Drop the open rate from your candidate updates, and watch your complaint rate the way you’d watch a tracking poll. To Gmail, it more or less is one.

The strongest programs in 2026 stop treating email like an island. It turns into the hub of a coordinated journey that also runs across SMS, RCS, peer-to-peer texts, and on-site retargeting, all of it sharing the same data and consent. RCS especially is dragging verified branding and rich, app-like messages into texting, until the line between “email” and “text” barely exists.

That’s a shift in how to think about the program: email as hub, not as the whole thing. A supporter who clicks your email, gets a well-timed text reminder, then a personal note from a volunteer is being guided through one experience. Compare that to being hit three times by three teams who never compare notes. The programs that win this cycle won’t be the ones sending the most email. They’ll be the ones building the best coordinated journey around it.

The play. Connect your email and texting data so the same person isn’t treated like a stranger from one channel to the next. Build a few simple handoffs (an email ask, an SMS nudge, P2P for your biggest supporters) and keep consent consistent the whole way through.

Last one, and it’s the trap campaigns fall into every cycle. Early and mail-in voting now opens as much as 45 days before Election Day, so a big share of the votes are in roughly six weeks out. The 2025 specials made this clear: no race waits for November. The whole money and turnout calendar slid forward, and email has to move with it.

Sending capacity isn’t something you can summon in October. A domain that has to email its full list every day down the stretch earns that by ramping for months, starting with your most engaged people and raising frequency in steps. The warm-up that campaigns once kicked off in late summer needs to start in spring, and your GOTV email program should begin the day early voting opens, not on the morning of Election Day.

The play. Plan backward from the first day of early voting in your state instead of from Election Day. Start warming and ramping now, so the trust and the capacity are already in the bank when you need to send daily.
